Package        : libxpm
Version        : 1:3.5.12-1+deb10u1
CVE ID         : CVE-2022-4883 CVE-2022-44617 CVE-2022-46285

libxpm is a library handling X PixMap image format (so called xpm files).
xpm files are an extension of the monochrome X BitMap format specified
in the X protocol, and is commonly used in traditional X applications.

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.
