CVE-2011-1658: GNU Glibc

Low severity, CVSS 3.7. EPSS: 0.3% chance of exploitation in the next 30 days.

ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token when RPATH is composed entirely of this token, which might allow local users to gain privileges by creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard operating-system distribution would ship an applicable setuid or setgid program.

Affected products

• GNU Glibc: up to and including 2.13; version 1.00 only; version 1.01 only; version 1.02 only; version 1.03 only; version 1.04 only; …
