Summary
Fix CVE(s): CVE-2026-33846, CVE-2026-42009
Details
  • SECURITY UPDATE: heap buffer overflow in DTLS handshake reassembly
    • debian/patches/CVE-2026-33846.patch: add length-consistency and array bounds checks in merge_handshake_packet in lib/gnutls_buffers.c to reject DTLS fragments with mismatching or oversized claimed length
    • CVE-2026-33846
  • SECURITY UPDATE: denial of service via non-conforming qsort comparator
    • debian/patches/CVE-2026-42009.patch: return 0 for equal sequence numbers in handshake_compare in lib/gnutls_buffers.c so DTLS packet ordering follows the qsort strict-weak-ordering contract
    • CVE-2026-42009
