Detailsinfo

A vulnerability has been found in GNOME gdk-pixbuf up to 2.42.1 and classified as problematic. Affected by this vulnerability is the function write_indexes of the file lzw.c of the component LZW Compression Handler. The manipulation with an unknown input leads to a infinite loop vulnerability. The CWE definition for the vulnerability is CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. As an impact it is known to affect availability. The summary by CVE is:

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.

The weakness was shared 12/26/2020. It is possible to read the advisory at bugs.debian.org. This vulnerability is known as CVE-2020-29385. Technical details of the vulnerability are known, but there is no available exploit.
