CVE-2010-3856: GNU Glibc

High severity, CVSS 7.2. EPSS: 11.2% chance of exploitation in the next 30 days.

ld.so in the GNU C Library (aka glibc or libc6) before 2.11.3, and 2.12.x before 2.12.2, does not properly restrict use of the LD_AUDIT environment variable to reference dynamic shared objects (DSOs) as audit objects, which allows local users to gain privileges by leveraging an unsafe DSO located in a trusted library directory, as demonstrated by libpcprofile.so.

Affected products

• GNU Glibc: up to and including 2.11.2; version 1.00 only; version 1.01 only; version 1.02 only; version 1.03 only; version 1.04 only; …
