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.
