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.
