Description OSIDB Bzimport 2025-04-15 01:32:23 UTC
A double-free vulnerability exists in GnuTLS (confirmed in version 3.8.9) due to incorrect
ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an
otherName. If the type-id OID is invalid or malformed, GnuTLS will call
asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free
condition when the parent function or caller later attempts to free the same structure.
This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of
service or memory corruption, depending on allocator behavior.
