Hi,

The following vulnerability was published for inetutils.

CVE-2023-40303[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
