Package : inetutils
Version : 2:1.9.4-7+deb10u3
CVE ID : CVE-2019-0053 CVE-2023-40303
Debian Bug : 945861 1049365
Security issues were discovered in inetutils, a collection of GNU
network utilities, which could lead to privilege escalation or
potentially execution of arbitrary code.
CVE-2019-0053
Thorsten Alteholz discovered that CVE-2019-0053 was patched
incorrectly in inetutils 2:1.9.4-7+deb10u3. The original
vulnerability remained: inetutils' telnet client doesn't
sufficiently validate environment variables, which can lead to
stack-based buffer overflows. (This issue is limited to local
exploitation from restricted shells.)
CVE-2023-40303
Jeffrey Bencteux discovered that several setuid(), setgid(),
seteuid() and setguid() return values were not checked in ftpd/
rcp/rlogin/rsh/rshd/uucpd code, which may lead to privilege
escalation.
For Debian 10 buster, these problems have been fixed in version
2:1.9.4-7+deb10u3.
We recommend that you upgrade your inetutils packages.
