Debian 10: DLA-3459-1 Moderate: libxpm Denial of Service Exploits

CVE-2022-4883

When processing files with
.Z or .gz extensions, the library calls external programs
to compress and uncompress files, relying on the
PATH environment variable to find these programs,
which could allow a malicious user to execute other programs
by manipulating the PATH environment variable.

CVE-2022-44617

When processing a file with width of 0
and a very large height, some parser functions will be
called repeatedly and can lead to an infinite loop,
resulting in a Denial of Service in the application linked
to the library.

CVE-2022-46285

When parsing a file with a comment
not closed, an end-of-file condition will not be detected,
leading to an infinite loop and resulting in a
Denial of Service in the application linked to the library.

For Debian 10 buster, these problems have been fixed in version
1:3.5.12-1+deb10u1.

We recommend that you upgrade your libxpm packages.
