A vulnerability has been identified in GnuTLS, which could be exploited by attackers to cause a denial of service or compromise a vulnerable system. This issue is caused by a use after free error in the "_gnutls_handshake_hash_buffers_clear()" [lib/gnutls_handshake.c] function when a peer calls "gnutls_handshake" within a normal session, which could cause the libgnutls libray to attempt to access to a deallocated libgcrypt handle, leading to a crash.
