Fedora 33 : gdk-pixbuf2 / gdk-pixbuf2-xlib (2021-2e59756cbe)

high Nessus Plugin ID 146746

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 33 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2021-2e59756cbe advisory.

 - GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way. (CVE-2020-29385)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected gdk-pixbuf2 and / or gdk-pixbuf2-xlib packages.
