36b18d8bf5e856d89167ab80984426474aa42f653d222293148657909f967893A buffer overflow exists in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. It has been dubbed Looney Tunables. This issue allows an local attacker to use maliciously crafted GLIBC_TUNABLES when launching binaries with SUID permission to execute code in the context of the root user. This Metasploit module targets glibc packaged on Ubuntu and Debian. Fedora 37 and 38 and other distributions of linux also come packaged with versions of glibc vulnerable to CVE-2023-4911 however this module does not target them.

An attacker could possibly use this issue to perform a privilege escalation attack. It was discovered that the GNU C Library incorrectly handled certain DNS responses when the system was configured in no-aaaa mode. A remote attacker could possibly use this issue to cause the GNU C Library to crash, resulting in a denial of service. This issue only affected Ubuntu 23.04.
