  script_tag(name:"insight", value:"Updated glibc packages fix security vulnerability:

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 (CVE-2021-3999).
