SSL/TLS implementations accept export-grade RSA keys (FREAK attack)
Overview Some implementations of SSL/TLS accept export-grade 512-bit or smaller RSA keys even when not specifically requesting export grade ciphers. An attacker able to act as a Man-in-The-Middle MiTM could factor weak temporary RSA keys, obtain session keys, and decrypt SSL/TLS trafflc. This iss...
New FREAK Attack Threatens Many SSL Clients
For the nth time in the last couple of years, security experts are warning about a new Internet-scale vulnerability, this time in some popular SSL clients. The flaw allows an attacker to force clients to downgrade to weakened ciphers and break their supposedly encrypted communications through a...
SUSE-SU-2015:0305-1 Security update for compat-openssl098
The openssl 0.9.8j compatibility package was updated to fix several security vulnerabilities: CVE-2014-3570: Bignum squaring BNsqr may produce incorrect results on some platforms, including x8664. CVE-2014-3571: Fix crash in dtls1getrecord whilst in the listen state where you get two separate rea...
SuSE 11.3 Security Update : compat-openssl097g (SAT Patch Number 10208)
OpenSSL compat-openssl097g has been updated to fix various security issues. More information can be found in the openssl advisory: http://openssl.org/news/secadv20150108.txt . The following issues have been fixed : - Bignum squaring BNsqr may have produced incorrect results on some platforms,...
openssl: only allow ephemeral RSA keys in export ciphersuites (FREAK)
It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method...
Oracle Solaris Third-Party Patch Update : libgcrypt (cve_2013_4242_information_disclosure)
The remote Solaris system is missing necessary patches to address security updates : - GnuPG before 1.4.14, and Libgcrypt before 1.5.3 as used in GnuPG 2.0.x and possibly other products, allows local users to obtain private RSA keys via a cache side-channel attack involving the L3 cache, aka...

F5 Networks BIG-IP : Hosts may generate weak RSA keys under low entropy conditions (SOL13607)
A recent study, linked in the Supplemental Information section, has revealed that when a system generates new RSA keys under low-entropy conditions, such as during the first system boot, the resulting keys may not be cryptographically strong. C Tenable Network Security, Inc. The descriptive text...
Amazon Linux AMI : gnupg (ALAS-2014-278)
GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not...

CVE-2013-4576
GnuPG 1.x before 1.4.16 is vulnerable to a side-channel attack during RSA key handling. The issue arises from sequences of introductions with certain patterns that enable a local attacker to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. The impact i...

US-CERT Warns of More CryptoLocker Ransomware Infections
CryptoLocker is a devious evolution of now-familiar ransomware schemes in which the malware encrypts files it finds on a number of network resources and demands a ransom for the decryption key. US-CERT issued an advisory today warning businesses and consumers of the risks presented by CryptoLocke...
