Descriptions

Use-after-free vulnerability in the _gnutls_handshake_hash_buffers_clear function in lib/gnutls_handshake.c in libgnutls in GnuTLS 2.3.5 through 2.4.0 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via TLS transmission of data that is improperly used when the peer calls gnutls_handshake within a normal session, leading to attempted access to a deallocated libgcrypt handle.

Vulnerabilidad de uso después de liberación en la función _gnutls_handshake_hash_buffers_clear de lib/gnutls_handshake.c en libgnutls de GnuTLS 2.3.5 hasta 2.4.0 permite a atacantes remotos provocar una denegación de servicio (caida) o posiblemente ejecutar código de su elección a través de transmisiones TLS de datos que no son usadas apropiadamente cuando las llamadas pares gnutls_handshake dentro de una sesión normal, conducen a intentos de acceso a manejadores libgcrypt no asignados.
