Threats affecting pkg:github/libcss

A NULL pointer dereference vulnerability exists in libcss up to version 0.9.2 within the netsurf-browser project. This flaw occurs in the mq_parse_media_query() function when processing media lists that end with a trailing comma. An attacker can exploit this by serving a stylesheet with an @media or @import media list ending in a comma, causing the parser to crash.
