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-2009-1415).

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-2009-1416).

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no longer valid, related to lack of time checks in the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

"The remote host is affected by the vulnerability described in GLSA-200905-04
(GnuTLS: Multiple vulnerabilities)

    The following vulnerabilities were found in GnuTLS:
    Miroslav Kratochvil reported that lib/pk-libgcrypt.c does not
    properly handle corrupt DSA signatures, possibly leading to a
    double-free vulnerability (CVE-2009-1415).
    Simon Josefsson
    reported that GnuTLS generates RSA keys stored in DSA structures when
    creating a DSA key (CVE-2009-1416).
    Romain Francoise reported
    that the _gnutls_x509_verify_certificate() function in
    lib/x509/verify.c does not perform time checks, resulting in the
    'gnutls-cli' program accepting X.509 certificates with validity times
    in the past or future (CVE-2009-1417).
  
Impact :

    A remote attacker could entice a user or automated system to process a
    specially crafted DSA certificate, possibly resulting in a Denial of
    Service condition. NOTE: This issue might have other unspecified impact
    including the execution of arbitrary code. Furthermore, a remote
    attacker could spoof signatures on certificates and the 'gnutls-cli'
    application can be tricked into accepting an invalid certificate.
  
Workaround :

    There is no known workaround at this time."
