View on CVE.org

Published Aug 14, 2023 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed

Description

GNU inetutils before 2.5 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.
