CVE-2010-3856

glibc: ld.so arbitrary DSO loading via LD_AUDIT in setuid/setgid programs

Published Jan 7, 2011 CVSS 2.0 · 7.2 High EPSS 12.3% KEV · Not listed
Description
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.
