No CVSS score has been assigned to CVE-2026-104064 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-104064?

Affected package information for CVE-2026-104064 is not yet fully mapped. Check the official advisory links for details.

How do I fix CVE-2026-104064?

Upgrade the affected component to the fixed release for CVE-2026-104064, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

How do I detect CVE-2026-104064 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-104064 if there is no patch (or I can't update yet)?

Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.

Is CVE-2026-104064 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-104064 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

CVE-2026-104064 was published on October 30, 2026 and was last updated on October 31, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

CVE-2026-104064: scribus Memory Corruption

Description

Scribus before 1.6.7 contains an integer overflow vulnerability in the scimgdataloader_tiff TIFF loader that allows attackers to trigger a heap overflow via crafted tile dimensions. Attackers can supply a tiled TIFF with large tile width, height and sample values for a user to import, corrupting heap memory to crash Scribus or execute code.
