CVE-2020-29385
https://notcve.org/view.php?id=CVE-2020-29385
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. GNOME gdk-pixbuf (también se conoce como GdkPixbuf) versiones anteriores a 2.42.2, permite una denegación de servicio (bucle infinito) en el archivo lzw.c en la función write_indexes. • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977166 https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/blob/master/NEWS https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/164 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/B5H3GNVWMZTYZR3JBYCK57PF7PFMQBNP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BGZVCTH5O7WBJLYXZ2UOKLYNIFPVR55D https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
