NVD Description

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

A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system.
