The remote Gentoo host is missing one or more security-related
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).
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).
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.
There is no known workaround at this time.
