Vulnerability from variot

Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. Multiple TCP Selective Acknowledgement (SACK) and Maximum Segment Size (MSS) networking vulnerabilities may cause denial-of-service conditions in Linux and FreeBSD kernels. A successful exploit could cause the targeted system to crash, resulting in a DoS condition. Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available. Kernel.org has confirmed the vulnerability and released software updates. ========================================================================== Kernel Live Patch Security Notice 0058-1 October 22, 2019

After a standard system update you need to reboot your computer to make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.

The following packages have been upgraded to a later upstream version: redhat-release-virtualization-host (4.3.4), redhat-virtualization-host (4.3.4). 7) - aarch64, noarch, ppc64le

  1. While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented. Each fragment is about TCP maximum segment size (MSS) bytes. To efficiently process SACK blocks, the Linux kernel merges multiple fragmented SKBs into one, potentially overflowing the variable holding the number of segments. A remote attacker could use this flaw to crash the Linux kernel by sending a crafted sequence of SACK segments on a TCP connection with small value of TCP MSS, resulting in a denial of service (DoS). (CVE-2019-11477)

  2. kernel: Double free in lib/idr.c (CVE-2019-3896)

  3. Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service (CVE-2019-11478)

  4. Kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service (CVE-2019-11479)

    "data": "Jonathan Looney discovered that the TCP_SKB_CB(skb)-\u003etcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. Multiple TCP Selective Acknowledgement (SACK) and Maximum Segment Size (MSS) networking vulnerabilities may cause denial-of-service conditions in Linux and FreeBSD kernels. A successful exploit could cause the targeted system to crash, resulting in a DoS condition. \nProof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available. \nKernel.org has confirmed the vulnerability and released software updates. ==========================================================================\nKernel Live Patch Security Notice 0058-1\nOctober 22, 2019\n\nlinux vulnerability\n==========================================================================\n\nA security issue affects these releases of Ubuntu:\n\n| Series           | Base kernel  | Arch     | flavors          |\n|------------------+--------------+----------+------------------|\n| Ubuntu 18.04 LTS | 4.15.0       | amd64    | aws              |\n| Ubuntu 18.04 LTS | 4.15.0       | amd64    | generic          |\n| Ubuntu 18.04 LTS | 4.15.0       | amd64    | lowlatency       |\n| Ubuntu 18.04 LTS | 4.15.0       | amd64    | oem              |\n| Ubuntu 18.04 LTS | 5.0.0        | amd64    | azure            |\n| Ubuntu 14.04 LTS | 4.4.0        | amd64    | generic          |\n| Ubuntu 14.04 LTS | 4.4.0        | amd64    | lowlatency       |\n| Ubuntu 16.04 LTS | 4.4.0        | amd64    | aws              |\n| Ubuntu 16.04 LTS | 4.4.0        | amd64    | generic          |\n| Ubuntu 16.04 LTS | 4.4.0        | amd64    | lowlatency       |\n| Ubuntu 16.04 LTS | 4.15.0       | amd64    | azure            |\n| Ubuntu 16.04 LTS | 4.15.0       | amd64    | generic          |\n| Ubuntu 16.04 LTS | 4.15.0       | amd64    | lowlatency       |\n\nSummary:\n\nSeveral security issues were fixed in the kernel. \n\nSoftware Description:\n- linux: Linux kernel\n\nDetails:\n\nIt was discovered that a race condition existed in the GFS2 file system in\nthe Linux kernel.

a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. These packages include redhat-release-virtualization-host,\novirt-node, and rhev-hypervisor. RHVH features a Cockpit user\ninterface for monitoring the host\u0027s resources and performing administrative\ntasks. \n\nThe following packages have been upgraded to a later upstream version:\nredhat-release-virtualization-host (4.3.4), redhat-virtualization-host\n(4.3.4). 7) - aarch64, noarch, ppc64le\n\n3. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n====================================================================                   \nRed Hat Security Advisory\n\nSynopsis:          Important: kernel security and bug fix update\nAdvisory ID:       RHSA-2019:1488-01\nProduct:           Red Hat Enterprise Linux\nAdvisory URL:      https://access.redhat.com/errata/RHSA-2019:1488\nIssue date:        2019-06-17\nCVE Names:         CVE-2019-3896 CVE-2019-11477 CVE-2019-11478\n                   CVE-2019-11479\n====================================================================\n1. Summary:\n\nAn update for kernel is now available for Red Hat Enterprise Linux 6. \n\nRed Hat Product Security has rated this update as having a security impact\nof Important. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\n2.

While processing SACK segments, the Linux kernel\u0027s socket buffer\n(SKB) data structure becomes fragmented. Each fragment is about TCP maximum\nsegment size (MSS) bytes. To efficiently process SACK blocks, the Linux\nkernel merges multiple fragmented SKBs into one, potentially overflowing\nthe variable holding the number of segments. A remote attacker could use\nthis flaw to crash the Linux kernel by sending a crafted sequence of SACK\nsegments on a TCP connection with small value of TCP MSS, resulting in a\ndenial of service (DoS). (CVE-2019-11477)\n\n* kernel: Double free in lib/idr.c (CVE-2019-3896)\n\n* Kernel: tcp: excessive resource consumption while processing SACK blocks\nallows remote denial of service (CVE-2019-11478)\n\n* Kernel: tcp: excessive resource consumption for TCP connections with low\nMSS allows remote denial of service (CVE-2019-11479)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, acknowledgments, and other related information, refer to the CVE\npage(s) listed in the References section. \n\nBug Fix(es):\n\n* MDS mitigations not enabled on Intel Skylake CPUs (BZ#1710081)\n\n* RHEL6 kernel does not disable SMT with mds=full,nosmt (BZ#1710121)\n\n* [RHEL6] md_clear flag missing from /proc/cpuinfo (BZ#1710517)\n\n4.
