Gnu · Gnu Inetutils · 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.
