gsd-2023-4911
Vulnerability from gsd
Modified
2023-12-13 01:20
Details
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.

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.
