A subtle bug in GnuTLS’s certificate-chain handling can be forced into crashing the library when presented with a specially crafted chain that uses distributed trust — a denial-of-service flaw tracked as CVE-2024-0567 that affected upstream releases before a patch was shipped and has since been...

A newly published vulnerability in GnuTLS — tracked as CVE-2025-6395 — allows a remote attacker to trigger a NULL pointer dereference in the library’s _gnutls_figure_common_ciphersuite() routine, producing memory corruption and reliable denial‑of‑service (DoS) outcomes for processes that parse...

GnuTLS’s certtool template-parsing bug tracked as CVE-2025-32990 is real and was mapped by Microsoft to its Azure Linux product family — but the simple sentence on the MSRC CVE page does not mean Azure Linux is the only Microsoft artifact that can contain GnuTLS. Microsoft’s wording is a...

A double‑free in GnuTLS’s Subject Alternative Name export logic — tracked as CVE‑2025‑32988 — can be triggered by a crafted certificate containing an otherName SAN with a malformed type‑id OID, allowing the library to free the same ASN.1 node twice (via asn1_delete_structure()), which in real...

The short answer is: Microsoft has publicly attested that the Azure Linux distribution includes the vulnerable GnuTLS component for CVE‑2025‑32989, but that attestation is product‑scoped — it is not proof that no other Microsoft product or image can include the same upstream library. In...

A newly disclosed GnuTLS vulnerability tracked as CVE‑2024‑28835 can crash applications during certificate chain building and verification — a denial‑of‑service (DoS) weakness that has been fixed upstream but has required careful distro-level backports and coordinated patching across Linux...
