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of X.509 certificates, which allows remote attackers to successfully present a certificate that is 1 not yet valid or 2 no longer valid, related to lack of time checks in the gnutlsx509verifycertificate function...

CVE-2009-1416: Undefined Security Weakness

lib/gnutlspk.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...

Mandriva Linux Security Advisory : gnutls (MDVSA-2008:227-1)

Martin von Gagern found a flow in how GnuTLS versions 1.2.4 up until 2.6.1 verified certificate chains provided by a server. A malicious server could use this flaw to spoof its identity by tricking client applications that used the GnuTLS library to trust invalid certificates CVE-2008-4989. Updat...

FreeBSD : gnutls -- certificate chain verification DoS (84ab58cf-e4ac-11d8-9b0a-000347a4fa7d)

Patric Hornik reports on a problem in the certificate chain verification procedures of GnuTLS that may result in a denial-of-service vulnerability : The certificate chain should be verified from last root certificate to the first certificate. Otherwise a lot of unauthorized CPU processing can be...

Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : gnutls12, gnutls13, gnutls26 vulnerability (USN-678-1)

Martin von Gagern discovered that GnuTLS did not properly verify certificate chains when the last certificate in the chain was self-signed. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. CVE-2008-4989. Note that...

Mandriva Linux Security Advisory : gnutls (MDVSA-2008:106)

Flaws discovered in versions prior to 2.2.4 stable and 2.3.10 development of GnuTLS allow an attacker to cause denial of service application crash, and maybe so far undetermined execute arbitrary code. The updated packages have been patched to fix these flaws. Note that any applications using thi...

Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : gnutls12, gnutls13, gnutls26 regression (USN-678-2)

USN-678-1 fixed a vulnerability in GnuTLS. The upstream patch introduced a regression when validating certain certificate chains that would report valid certificates as untrusted. This update fixes the problem. We apologize for the inconvenience. Martin von Gagern discovered that GnuTLS did not...
