Vulnerability from variot
In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no longer supported by ISC. From inspection it is clear that the defect is also present in releases from those series, but they have not been officially tested for the vulnerability), The outcome of encountering the defect while reading a lease that will trigger it varies, according to: the component being affected (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when reading an improper lease, which could cause network connectivity problems for an affected system due to the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in lack of service to clients. Additionally, the offending lease and the lease immediately following it in the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not occur, but it is possible for the offending lease and the lease which immediately followed it to be improperly deleted. There is a discrepancy between the code that handles encapsulated option information in leases transmitted "on the wire" and the code which reads and parses lease information after it has been written to disk storage. The highest threat from this vulnerability is to data confidentiality and integrity as well as service availability. (CVE-2021-25217). -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

Red Hat Enterprise Linux Server AUS (v. 7.6) - x86_64 Red Hat Enterprise Linux Server E4S (v. 7.6) - ppc64le, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 7.6) - x86_64 Red Hat Enterprise Linux Server Optional E4S (v. 7.6) - ppc64le, x86_64 Red Hat Enterprise Linux Server Optional TUS (v. 7.6) - x86_64 Red Hat Enterprise Linux Server TUS (v. 7.6) - x86_64
- Description:
The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address. The dhcp packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network.
Security Fix(es):
- dhcp: stack-based buffer overflow when parsing statements with colon-separated hex digits in config or lease files in dhcpd and dhclient (CVE-2021-25217)

USN-4969-1 fixed a vulnerability in DHCP. This update provides the corresponding update for Ubuntu 14.04 ESM and 16.04 ESM.
Original advisory details:
Jon Franklin and Pawel Wieczorkiewicz discovered that DHCP incorrectly handled lease file parsing. A remote attacker could possibly use this issue to cause DHCP to crash, resulting in a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 ESM: isc-dhcp-client 4.3.3-5ubuntu12.10+esm1 isc-dhcp-server 4.3.3-5ubuntu12.10+esm1
Ubuntu 14.04 ESM: isc-dhcp-client 4.2.4-7ubuntu12.13+esm1 isc-dhcp-server 4.2.4-7ubuntu12.13+esm1

"data": "In ISC DHCP 4.1-ESV-R1 -\u003e 4.1-ESV-R16, ISC DHCP 4.4.0 -\u003e 4.4.2 (Other branches of ISC DHCP (i.e., releases in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no longer supported by ISC. From inspection it is clear that the defect is also present in releases from those series, but they have not been officially tested for the vulnerability), The outcome of encountering the defect while reading a lease that will trigger it varies, according to: the component being affected (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when reading an improper lease, which could cause network connectivity problems for an affected system due to the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in lack of service to clients. Additionally, the offending lease and the lease immediately following it in the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not occur, but it is possible for the offending lease and the lease which immediately followed it to be improperly deleted. There is a discrepancy between the code that handles encapsulated option information in leases transmitted \"on the wire\" and the code which reads and parses lease information after it has been written to disk storage. The highest threat from this vulnerability is to data confidentiality and integrity as well as service availability. (CVE-2021-25217). -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: dhcp security update\nAdvisory ID: RHSA-2021:2469-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2021:2469\nIssue date: 2021-06-17\nCVE Names: CVE-2021-25217 \n=====================================================================\n\n1.
