CVE-2009-1415
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.

CVE-2009-1416
lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates
RSA keys stored in DSA structures, instead of the intended DSA keys,
which might allow remote attackers to spoof signatures on certificates
or have unspecified other impact by leveraging an invalid DSA key.

CVE-2009-1417
gnutls-cli in GnuTLS before 2.6.6 does not verify the activation and
expiration times of X.509 certificates, which allows remote attackers
to successfully present a certificate that is (1) not yet valid or (2)
no longer valid, related to lack of time checks in the
_gnutls_x509_verify_certificate function in lib/x509/verify.c in
libgnutls_x509, as used by (a) Exim, (b) OpenLDAP, and (c) libsoup.");
