Ubuntu Security Notice USN-5658-3

Ubuntu Security Notice 5658-3 - USN-5658-1 fixed several vulnerabilities in DHCP. This update provides the corresponding update for Ubuntu 14.04 ESM. It was discovered that DHCP incorrectly handled option reference counting. A remote attacker could possibly use this issue to cause DHCP servers to crash, resulting in a denial of service.

Ubuntu Security Notice 5658-3 - USN-5658-1 fixed several vulnerabilities in DHCP. This update provides the corresponding update for Ubuntu 14.04 ESM. It was discovered that DHCP incorrectly handled option reference counting. A remote attacker could possibly use this issue to cause DHCP servers to crash, resulting in a denial of service.

CVE-2022-2928: CVE-2022-2928 An option refcount overflow exists in dhcpd

In ISC DHCP 4.4.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1, when the function option_code_hash_lookup() is called from add_option(), it increases the option's refcount field. However, there is not a corresponding call to option_dereference() to decrement the refcount field. The function add_option() is only used in server responses to lease query packets. Each lease query response calls this function for several options, so eventually, the reference counters could overflow and cause the server to abort.

CVE-2022-2929: CVE-2022-2929 DHCP memory leak

In ISC DHCP 1.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1 a system with access to a DHCP server, sending DHCP packets crafted to include fqdn labels longer than 63 bytes, could eventually cause the server to run out of memory.

Ubuntu Security Notice USN-5658-1

Ubuntu Security Notice 5658-1 - It was discovered that DHCP incorrectly handled option reference counting. A remote attacker could possibly use this issue to cause DHCP servers to crash, resulting in a denial of service. It was discovered that DHCP incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause DHCP clients and servers to consume resources, leading to a denial of service.

CVE-2021-25217: CVE-2021-25217: A buffer overrun in lease file parsing code

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...
