CVE-2023-4208 (GCVE-0-2023-4208)
Vulnerability from cvelistv5 – Published: 2023-09-06 13:53 – Updated: 2025-02-13 17:09

Title
Use-after-free in Linux kernel's net/sched: cls_u32 component
Summary
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation.
When u32_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free.
We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81.

CVE-2023-4527 (GCVE-0-2023-4527)
Vulnerability from cvelistv5 – Published: 2023-09-18 16:32 – Updated: 2026-05-12 10:12

Title
Glibc: stack read overflow in getaddrinfo in no-aaaa mode
Summary
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
Severity
6.5 (Medium)

Exploitation: none
Automatable: no
Technical Impact: partial

Title
Glibc: potential use-after-free in getaddrinfo()
Summary
A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
Severity

Title
Glibc: potential use-after-free in gaih_inet()
Summary
A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.

When enabled, any setuid program invoked with GLIBC_TUNABLES in the environment will be terminated immediately. To invoke the setuid program, users will then have to unset or clear the GLIBC_TUNABLES envvar, e.g. `GLIBC_TUNABLES= sudo` . \n\nNote that these mitigation steps will need to be repeated if the system is rebooted.\n\n1) Install required systemtap packages and dependencies as per - https://access.redhat.com/solutions/5441\n\n\n2) Create the following systemtap script, and name it stap_block_suid_tunables.stp:\n ~~~\nfunction has_tunable_string:long()\n{\n name = \"GLIBC_TUNABLES\"\n\n mm = @task(task_current())-\u003emm;\n if (mm)\n {\n env_start = @mm(mm)-\u003eenv_start;\n env_end = @mm(mm)-\u003eenv_end;\n\n if (env_start != 0 \u0026\u0026 env_end != 0)\n while (env_end \u003e env_start)\n {\n cur = user_string(env_start, \"\");\n env_name = tokenize(cur, \"=\");\n \n if (env_name == name \u0026\u0026 tokenize(\"\", \"\") != \"\")\n return 1;\n env_start += strlen (cur) + 1\n }\n }\n\n return 0;\n}\n\nprobe process(\"/lib*/ld*.so*\").function(\"__tunables_init\")\n{\n atsecure = 0;\n /* Skip processing if we can\u0027t read __libc_enable_secure, e.g. core dump\n handler (systemd-cgroups-agent and systemd-coredump). */\n try { atsecure = @var(\"__libc_enable_secure\"); }\n catch { printk (4, sprintf (\"CVE-2023-4911: Skipped check: %s (%d)\", execname(), pid())); }\n if (atsecure \u0026\u0026 has_tunable_string ())\n raise (9);\n}\n~~~\n\n3) Load the systemtap module into the running kernel:\n ~~~\n stap -g -F -m stap_block_suid_tunables stap_block_suid_tunables.stp\n ~~~\n\n4) Ensure the module is loaded:\n ~~~\n lsmod | grep -i stap_block_suid_tunables\nstap_block_suid_tunables 249856 0\n~~~\n\n5) Once the glibc package is updated to the version containing the fix, the systemtap generated kernel module can be removed by running:\n ~~~\n rmmod stap_block_suid_tunables\n ~~~\n\nIf Secure Boot is enabled on a system, the SystemTap module must be signed. An external compiling server can be used to sign the generated kernel module with a key enrolled into the kernel\u0027s keyring or starting with SystemTap 4.7 you can sign a module without a compile server.
