Summary
Fix CVE(s): CVE-2026-6653, CVE-2026-86143, CVE-2026-86144
Details
  • SECURITY UPDATE: use-after-free in the DTD parser reachable through parameter-entity references
    • debian/patches/CVE-2026-6653.patch: drop the post-inputPush XML_PARSER_EOF early return from xmlPushInput() in parser.c. It reported an already-halted parser as a push failure after ownership of the input had been transferred, so xmlParsePEReference() freed the input still installed as ctxt->input and xmlParseInternalSubset() read through the dangling pointer. The flaw is introduced by the CVE-2021-3541 backport, not by the shipped version.
    • CVE-2026-6653
