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of X.509 certificates, which allows remote attackers to successfully present a certificate that is 1 not yet valid or 2 no longer valid, related to lack of time checks in the gnutlsx509verifycertificate function...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-2009-1417

CVE-2009-1417 concerns gnutls-cli in GnuTLS prior to 2.6.6, where the time checks for X.509 certificates are not performed in _gnutls_x509_verify_certificate. This allows a remote attacker to present a certificate that is not yet valid or has expired, with downstream impact on affected apps (Exim...

CVE-2009-1416

GnuTLS CVE-2009-1416 affects GnuTLS 2.5.0–2.6.5: libgnutls/libgnutls_pk.c generates RSA keys and stores them in DSA structures, enabling remote attackers to spoof certificate signatures or cause unspecified impact via an invalid DSA key. Connected documents reference CVE IDs and advisories; no im...

CVE-2009-1415

CVE-2009-1415 affects GnuTLS up to version 2.6.5 (fixed in 2.6.6). The flaw resides in lib/pk-libgcrypt.c within libgnutls, which mishandles invalid DSA signatures. A malformed DSA key can trigger a denial of service (application crash) and may cause additional impact, including a free of an unin...

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 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...

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...

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...
