CVE-2023-40303

Name of the Vulnerable Software and Affected Versions GNU inetutils versions prior to 2.5

Description The issue allows privilege escalation due to unchecked return values of set*id() family functions in ftpd, rcp, rlogin, rsh, rshd, and uucpd. This is relevant if the setuid system call fails when a process is trying to drop privileges before letting an ordinary user control the activities of the process.

Recommendations For GNU inetutils versions prior to 2.5, update to version 2.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the set*id() family functions in the affected services until a patch is available.
