NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-langpack-cmn package and not the glibc-langpack-cmn package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
