Summary
Xenstore: Guests can create arbitrary number of nodes via transactions T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] In case a node has been created in a transaction and it is later deleted in the same transaction, the transaction will be terminated with an error. As this error is encountered only when handling the deleted node at transaction finalization, the transaction will have been performed partially and without updating the accounting information. This will enable a malicious guest to create arbitrary number of nodes.

By repeating this process over and over again an arbitrary number of nodes can be created, as Dom0's number of nodes isn't limited by Xenstore quota.", title: "CVE description", }, ], product_status: { recommended: [ "SUSE Linux Enterprise Server 12 SP5:xen-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-doc-html-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-libs-32bit-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-libs-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-tools-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-tools-domU-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-doc-html-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-libs-32bit-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-libs-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-tools-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-tools-domU-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Software Development Kit 12 SP5:xen-devel-4.12.4_30-3.82.1.aarch64", "SUSE Linux Enterprise Software Development Kit 12 SP5:xen-devel-4.12.4_30-3.82.1.x86_64", ], }, references: [ { category: "external", summary: "CVE-2022-42323", url: "https://www.suse.com/security/cve/CVE-2022-42323", }, { category: "external", summary: "SUSE Bug 1204494 for CVE-2022-42323", url: "https://bugzilla.suse.com/1204494", }, ], remediations: [ { category: "vendor_fix", details: "To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n", product_ids: [ "SUSE Linux Enterprise Server 12 SP5:xen-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-doc-html-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-libs-32bit-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-libs-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-tools-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-tools-domU-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-doc-html-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-libs-32bit-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-libs-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-tools-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-tools-domU-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Software Development Kit 12 SP5:xen-devel-4.12.4_30-3.82.1.aarch64", "SUSE Linux Enterprise Software Development Kit 12 SP5:xen-devel-4.12.4_30-3.82.1.x86_64", ], }, ], scores: [ { cvss_v3: { baseScore: 5.3, baseSeverity: "MEDIUM", vectorString: "CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:H", version: "3.1", }, products: [ "SUSE Linux Enterprise Server 12 SP5:xen-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-doc-html-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-libs-32bit-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-libs-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-tools-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server 12 SP5:xen-tools-domU-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-doc-html-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-libs-32bit-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-libs-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-tools-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:xen-tools-domU-4.12.4_30-3.82.1.x86_64", "SUSE Linux Enterprise Software Development Kit 12 SP5:xen-devel-4.12.4_30-3.82.1.aarch64", "SUSE Linux Enterprise Software Development Kit 12 SP5:xen-devel-4.12.4_30-3.82.1.x86_64", ], }, ], threats: [ { category: "impact", date: "2022-12-06T13:25:17Z", details: "moderate", }, ], title: "CVE-2022-42323", }, { cve: "CVE-2022-42325", ids: [ { system_name: "SUSE CVE Page", text: "https://www.suse.com/security/cve/CVE-2022-42325", }, ], notes: [ { category: "general", text: "Xenstore: Guests can create arbitrary number of nodes via transactions T[his CNA information record relates to multiple CVEs;

Speculative vulnerabilities with bare (non-shim) 32-bit PV guests 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to virtualization. In AMD64, Xen had to use a different implementation approach, so Xen does not use ring 1 to support 64-bit guests. With the focus now being on 64-bit systems, and the availability of explicit hardware support for virtualization, fixing speculation issues in ring 1 is not a priority for processor companies. Indirect Branch Restricted Speculation (IBRS) is an architectural x86 extension put together to combat speculative execution sidechannel attacks, including Spectre v2. It was retrofitted in microcode to existing CPUs. For more details on Spectre v2, see: http://xenbits.xen.org/xsa/advisory-254.html However, IBRS does not architecturally protect ring 0 from predictions learnt in ring 1. For more details, see: https://software.intel.com/security-software-guidance/deep-dives/deep-dive-indirect-branch-restricted-speculation Similar situations may exist with other mitigations for other kinds of speculative execution attacks.

CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Since the fix of XSA-322 any Xenstore node owned by a removed domain will be modified to be owned by Dom0. This will allow two malicious guests working together to create an arbitrary number of Xenstore nodes. This is possible by domain A letting domain B write into domain A's local Xenstore tree. Domain B can then create many nodes and reboot. The nodes created by domain B will now be owned by Dom0.

guests 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to virtualization. In AMD64, Xen had to use a different implementation approach, so Xen does not use ring 1 to support 64-bit guests. With the focus now being on 64-bit systems, and the availability of explicit hardware support for virtualization, fixing speculation issues in ring 1 is not a priority for processor companies. Indirect Branch Restricted Speculation (IBRS) is an architectural x86 extension put together to combat speculative execution sidechannel attacks, including Spectre v2. It was retrofitted in microcode to existing CPUs. For more details on Spectre v2, see: http://xenbits.xen.org/xsa/advisory-254.html However, IBRS does not architecturally protect ring 0 from predictions learnt in ring 1. For more details, see: https://software.intel.com/security-software-guidance/deep-dives/deep-dive-indirect-branch-restricted-speculation Similar situations may exist with other mitigations for other kinds of speculative execution attacks.

There is a small time window when a new domain is created, where the access rights of a past domain with the same domid as the new one will be regarded to be still valid, leading to the new domain being able to get access to a node which was meant to be accessible by the removed domain. For this to happen another domain needs to write the node before the newly created domain is being introduced to Xenstore by dom0.", title: "CVE description", }, ], product_status: { recommended: [

text: "x86: Speculative vulnerabilities with bare (non-shim) 32-bit PV guests 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to virtualization. In AMD64, Xen had to use a different implementation approach, so Xen does not use ring 1 to support 64-bit guests. With the focus now being on 64-bit systems, and the availability of explicit hardware support for virtualization, fixing speculation issues in ring 1 is not a priority for processor companies. Indirect Branch Restricted Speculation (IBRS) is an architectural x86 extension put together to combat speculative execution sidechannel attacks, including Spectre v2. It was retrofitted in microcode to existing CPUs. For more details on Spectre v2, see: http://xenbits.xen.org/xsa/advisory-254.html However, IBRS does not architecturally protect ring 0 from predictions learnt in ring 1. For more details, see: https://software.intel.com/security-software-guidance/deep-dives/deep-dive-indirect-branch-restricted-speculation Similar situations may exist with other mitigations for other kinds of speculative execution attacks. The situation is quite likely to be similar for speculative execution attacks which have yet to be discovered, disclosed, or mitigated.", title: "CVE description", }, ], product_status: { recommended:

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction", title: "CVE description", }, ], product_status: {

When a domain is gone, there might be Xenstore nodes left with access rights containing the domid of the removed domain. This is normally no problem, as those access right entries will be corrected when such a node is written later. There is a small time window when a new domain is created, where the access rights of a past domain with the same domid as the new one will be regarded to be still valid, leading to the new domain being able to get access to a node which was meant to be accessible by the removed domain. For this to happen another domain needs to write the node before the newly created domain is being introduced to Xenstore by dom0.", title: "CVE description", }, ], product_status: { recommended: [

aspects/vulnerabilities correspond to which CVE.] Since the fix of XSA-322 any Xenstore node owned by a removed domain will be modified to be owned by Dom0. This will allow two malicious guests working together to create an arbitrary number of Xenstore nodes. This is possible by domain A letting domain B write into domain A's local Xenstore tree. Domain B can then create many nodes and reboot. The nodes created by domain B will now be owned by Dom0.

aspects/vulnerabilities correspond to which CVE.] Since the fix of XSA-322 any Xenstore node owned by a removed domain will be modified to be owned by Dom0. This will allow two malicious guests working together to create an arbitrary number of Xenstore nodes. This is possible by domain A letting domain B write into domain A's local Xenstore tree. Domain B can then create many nodes and reboot. The nodes created by domain B will now be owned by Dom0.

Speculative vulnerabilities with bare (non-shim) 32-bit PV guests 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to virtualization. In AMD64, Xen had to use a different implementation approach, so Xen does not use ring 1 to support 64-bit guests. With the focus now being on 64-bit systems, and the availability of explicit hardware support for virtualization, fixing speculation issues in ring 1 is not a priority for processor companies. Indirect Branch Restricted Speculation (IBRS) is an architectural x86 extension put together to combat speculative execution sidechannel attacks, including Spectre v2. It was retrofitted in microcode to existing CPUs. For more details on Spectre v2, see: http://xenbits.xen.org/xsa/advisory-254.html However, IBRS does not architecturally protect ring 0 from predictions learnt in ring 1. For more details, see: https://software.intel.com/security-software-guidance/deep-dives/deep-dive-indirect-branch-restricted-speculation Similar situations may exist with other mitigations for other kinds of speculative execution attacks.

There is a small time window when a new domain is created, where the access rights of a past domain with the same domid as the new one will be regarded to be still valid, leading to the new domain being able to get access to a node which was meant to be accessible by the removed domain. For this to happen another domain needs to write the node before the newly created domain is being introduced to Xenstore by dom0.", title: "CVE description", }, ], product_status: { recommended: [ "SUSE Linux Enterprise Server 12 SP3-BCL:xen-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-doc-html-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-libs-32bit-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-libs-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-tools-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-tools-domU-4.9.4_34-3.114.1.x86_64", ], }, references: [ { category: "external", summary: "CVE-2022-42320", url: "https://www.suse.com/security/cve/CVE-2022-42320", }, { category: "external", summary: "SUSE Bug 1204489 for CVE-2022-42320", url: "https://bugzilla.suse.com/1204489", }, ], remediations: [ { category: "vendor_fix", details: "To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n", product_ids: [ "SUSE Linux Enterprise Server 12 SP3-BCL:xen-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-doc-html-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-libs-32bit-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-libs-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-tools-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-tools-domU-4.9.4_34-3.114.1.x86_64", ], }, ], scores: [ { cvss_v3: { baseScore: 7.5, baseSeverity: "HIGH", vectorString: "CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H", version: "3.1", }, products: [ "SUSE Linux Enterprise Server 12 SP3-BCL:xen-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-doc-html-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-libs-32bit-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-libs-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-tools-4.9.4_34-3.114.1.x86_64", "SUSE Linux Enterprise Server 12 SP3-BCL:xen-tools-domU-4.9.4_34-3.114.1.x86_64", ], }, ], threats: [ { category: "impact", date: "2022-11-11T14:43:06Z", details: "important", }, ], title: "CVE-2022-42320", }, { cve: "CVE-2022-42321", ids: [ { system_name: "SUSE CVE Page", text: "https://www.suse.com/security/cve/CVE-2022-42321", }, ], notes: [ { category: "general", text: "Xenstore: Guests can crash xenstored via exhausting the stack Xenstored is using recursion for some Xenstore operations (e.g. for deleting a sub-tree of Xenstore nodes).
