Ubuntu 14.04 LTS : GnuTLS vulnerability (USN-2229-1)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2229-1 advisory. Joonas Kuorilehto discovered that GnuTLS incorrectly handled Server Hello messages. A malicious remote server or a machine-in-the-middle could use this issue to...

TLS 1.3 Has Consensus to Deprectate RSA Key Transport

The IETF working group responsible for the TLS 1.3 standard is closing in on a decision to remove RSA key transport cipher suites from the protocol. Decades-old RSA-based handshakes don’t cut it anymore, according to experts, who are anxious to put a modern protocol in place, one that can fend of...

CVE-2014-0092

lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not properly handle unspecified errors when verifying X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers via a crafted certificate...

MGASA-2014-0077 Updated gnutls packages fix security vulnerability

Suman Jana reported a vulnerability that affects the certificate verification functions of gnutls 3.1.x and gnutls 3.2.x. A version 1 intermediate certificate will be considered as a CA certificate by default something that deviates from the documented behavior CVE-2014-1959...

UBUNTU-CVE-2013-4487

Off-by-one error in the danerawtlsa in the DANE library libdane in GnuTLS 3.1.x before 3.1.16 and 3.2.x before 3.2.6 allows remote servers to cause a denial of service memory corruption via a response with more than four DANE entries. NOTE: this issue is due to an incomplete fix for CVE-2013-4466...

CVE-2013-1619

The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks...

gnutls: unknown hash algorithm NULL pointer derefence [GNUTLS-SA-2006-2]

The gnutlsx509oid2macalgorithm function in lib/gnutlsalgorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service crash via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference...

CVE-2012-0390

The DTLS implementation in GnuTLS 3.0.10 and earlier executes certain error-handling code only if there is a specific relationship between a padding length and the ciphertext size, which makes it easier for remote attackers to recover partial plaintext via a timing side-channel attack, a related...

gnutls: gnutls_x509_crt_get_serial incorrect serial decoding from ASN1 (BE64) [GNUTLS-SA-2010-1]

The gnutlsx509crtgetserial function in the GnuTLS library before 1.2.1, when running on big-endian, 64-bit platforms, calls the asn1readvalue with a pointer to the wrong data type and the wrong length value, which allows remote attackers to bypass the certificate revocation list CRL check and cau...

deprecate MD2 in SSL cert validation (Kaminsky)

The Network Security Services NSS library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash...

CVE-2007-3564

libcurl 7.14.0 through 7.16.3, when built with GnuTLS support, does not check SSL/TLS certificate expiration or activation dates, which allows remote attackers to bypass certain access restrictions...
