"The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dsa-5228 advisory.

  - GNOME gdk-pixbuf 2.42.6 is vulnerable to a heap-buffer overflow vulnerability when decoding the lzw
    compressed stream of image data in GIF files with lzw minimum code size equals to 12. (CVE-2021-44648)

  - GNOME GdkPixbuf (aka GDK-PixBuf) before 2.42.8 allows a heap-based buffer overflow when compositing or
    clearing frames in GIF files, as demonstrated by io-gif-animation.c composite_frame. This overflow is
    controllable and could be abused for code execution, especially on 32-bit systems. (CVE-2021-46829)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
