# CVE-2026-16118: Xdgmime: heap-based buffer overflow in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c Status: published. Published: 2026-07-17. Updated: 2026-11-05. 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. ## Remediation - workaround: Do not install a MIME magic file or content from untrusted sources. (source: CNA: redhat) ## Affected products and versions - xdg / xdgmime (xdgmime): Version range not reported.
