MGASA-2015-0322 Updated gnutls packages fix security vulnerabilities
It was reported that GnuTLS does not check whether the two signature algorithms match on certificate import CVE-2015-0294. Kurt Roeckx discovered that decoding a specific certificate with very long DistinguishedName DN entries leads to double free. A remote attacker can take advantage of this fla...

NSS: ECDSA signature validation fails to handle some signatures correctly (MFSA 2015-64)
A flaw was found in the way NSS verified certain ECDSA Elliptic Curve Digital Signature Algorithm signatures. Under certain conditions, an attacker could use this flaw to conduct signature forgery attacks...
Updated libcryptopp package fixes security vulnerability
Evgeny Sidorov discovered that libcryptopp did not properly implement blinding to mask private key operations for the Rabin-Williams digital signature algorithm. This could allow remote attackers to mount a timing attack and retrieve the user's private key CVE-2015-2141...
Amazon Linux AMI : gnutls (ALAS-2015-575)
It was found that GnuTLS did not check activation and expiration dates of CA certificates. This could cause an application using GnuTLS to incorrectly accept a certificate as valid when its issuing CA is already expired. CVE-2014-8155 It was found that GnuTLS did not verify whether a hashing...
gnutls: certificate algorithm consistency checking issue
It was discovered that GnuTLS did not check if all sections of X.509 certificates indicate the same signature algorithm. This flaw, in combination with a different flaw, could possibly lead to a bypass of the certificate signature check...
openSUSE Security Update : libcryptopp (openSUSE-2015-504)
libcryptopp was updated to fix one security issue. This security issue was fixed : - CVE-2015-2141: The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 did not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allowed...
CVE-2015-2141
libcrypt++ 5.6.2 contains a timing-attack vulnerability in InvertibleRWFunction::CalculateInverse used with Rabin–Williams signatures, enabling remote extraction of private keys. Affected component is the private-key blinding during Rabin–Williams operations; impact is private-key disclosure unde...
OpenJDK: insufficient hardening of RSA-CRT implementation (JCE, 8071726)
It was found that the RSA implementation in the JCE component in OpenJDK did not follow recommended practices for implementing RSA signatures...
Debian DLA-180-1 : gnutls26 security update
Multiple vulnerabilities have been discovered in GnuTLS, a library implementing the TLS and SSL protocols. The Common Vulnerabilities and Exposures project identifies the following problems : CVE-2014-8155 Missing date/time checks on CA certificates CVE-2015-0282 GnuTLS does not verify the RSA PK...
Code injection
GnuTLS before 3.1.0 does not verify that the RSA PKCS 1 signature algorithm matches the signature algorithm in the certificate, which allows remote attackers to conduct downgrade attacks via unspecified vectors...
CVE-2015-0282
GnuTLS before 3.1.0 does not verify that the RSA PKCS#1 signature algorithm matches the signature algorithm in the certificate, enabling remote downgrade attacks via unspecified vectors. Impact is downgrade/traffic manipulation risk with affected deployments. The CVE entry explicitly targets GnuTLS...
USN-2540-1 gnutls26, gnutls28 vulnerabilities
It was discovered that GnuTLS did not perform date and time checks on CA certificates, contrary to expectations. This issue only affected Ubuntu 10.04 LTS. CVE-2014-8155 Nikos Mavrogiannopoulos discovered that GnuTLS incorrectly verified that signature algorithms matched. A remote attacker could...

cryptopp -- multiple vulnerabilities
Multiple sources report: CVE-2015-2141: The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack...
Mandriva Linux Security Advisory : openssl (MDVSA-2015:019)
Multiple vulnerabilities has been discovered and corrected in openssl : A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack CVE-2014-3571. A memory leak can occur in the dtls1bufferrecord...
Updated openssl packages fix security vulnerabilities
A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack CVE-2014-3571. A memory leak can occur in the dtls1bufferrecord function under certain conditions. In particular this could occur if an...
