Hi, The following vulnerability was published for glib2.0. CVE-2026-1485[0]: | A flaw was found in Glib's content type parsing logic. This buffer | underflow vulnerability occurs because the length of a header line | is stored in a signed integer, which can lead to integer wraparound | for very large inputs. This results in pointer underflow and out-of- | bounds memory access. Exploitation requires a local user to install | or process a specially crafted treemagic file, which can lead to | local denial of service or application instability. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
