CVE-2005-3590: glibc: buffer overflow in getgrouplist function leading to corrupted memory

Severity: Critical

CVSS Score: 9.8

The getgrouplist function in the GNU C library (glibc) before version 2.3.5, when invoked with a zero argument, writes to the passed pointer even if the specified array size is zero, leading to a buffer overflow and potentially allowing attackers to corrupt memory.
