CVE-2025-32988
Full vulnerability record from the local CVENow database.
Description
A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS 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.

"value": "Se encontró una falla en GnuTLS. Existe una vulnerabilidad de doble liberación debido a una gestión incorrecta de la propiedad en la lógica de exportación de las entradas de Nombre Alternativo del Sujeto (SAN) que contienen un otro nombre. Si el OID de tipo no es válido o está mal formado, GnuTLS llamará a asn1_delete_structure() en un nodo ASN.1 que no le pertenece, lo que genera una condición de doble liberación cuando la función principal o el invocador intenta posteriormente liberar la misma estructura. Esta vulnerabilidad puede activarse utilizando únicamente las API públicas de GnuTLS y puede provocar denegación de servicio o corrupción de memoria, según el comportamiento del asignador."
