CVE ID         : CVE-2021-44648 CVE-2021-46829
Debian Bug     : 1014600

Several vulnerabilities were discovered in gdk-pixbuf, the GDK
Pixbuf library.

CVE-2021-44648

    Sahil Dhar reported a heap-based buffer overflow vulnerability when
    decoding the lzw compressed stream of image data, which may result
    in the execution of arbitrary code or denial of service if a
    malformed GIF image is processed.

CVE-2021-46829

    Pedro Ribeiro reported a heap-based buffer overflow vulnerability
    when compositing or clearing frames in GIF files, which may result
    in the execution of arbitrary code or denial of service if a
    malformed GIF image is processed.

For the stable distribution (bullseye), these problems have been fixed in
version 2.42.2+dfsg-1+deb11u1.

We recommend that you upgrade your gdk-pixbuf packages.
