Fedora 33 : mingw-gdk-pixbuf (2021-755ba8968a)

high Nessus Plugin ID 147770

Language:

Synopsis

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

Description

The remote Fedora 33 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-755ba8968a 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 mingw-gdk-pixbuf package.
