The version of webkitgtk4 installed on the remote host is prior to 2.52.5-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3843 advisory.

    A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in
    _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-     controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic     path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When     performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2     bytes, resulting in an application crash or memory corruption. (CVE-2026-16118)
