Oracle Linux: CVE-2021-3999: ELSA-2022-0896: glibc security update (MODERATE) (Multiple Advisories)

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.
