## Description

lib/pk-libgcrypt.c in libgnutls in GnuTLS before 2.6.6 does not properly
handle invalid DSA signatures, which allows remote attackers to cause a
denial of service (application crash) and possibly have unspecified other
impact via a malformed DSA key that triggers a (1) free of an uninitialized
pointer or (2) double free.
