A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLSdue to incorrect ownership handling in the export logic of SubjectAlternative Name (SAN) entries containing an otherName. If the type-id OIDis invalid or malformed, GnuTLS will call asn1_delete_structure() on anASN.1 node it does not own, leading to a double-free condition when theparent function or caller later attempts to free the same structure.This vulnerability can be triggered using only public GnuTLS APIs and mayresult in denial of service or memory corruption, depending on allocatorbehavior.
