GSD-2023-40303

Vulnerability from gsd - Updated: 2023-12-13 01:20
Details
GNU inetutils through 2.4 may allow privilege escalation because of unchecked return values of set*id() family functions in ftpd, rcp, rlogin, rsh, rshd, and uucpd. This is, for example, 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.
