UBUNTU-CVE-2016-7141

curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has...

Internet Bug Bounty: FREAK: Factoring RSA_EXPORT Keys to Impersonate TLS Servers

Many TLS servers, including those hosting sensitive websites such as www.nsa.gov and connect.facebook.net, support weak EXPORTRSA ciphersuites. By factoring their 512-bit ephemeral RSA keys, a network attacker is able to impersonate these websites to web browsers and more generally, to client...

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...

openSUSE Security Update : docker / go (openSUSE-SU-2014:1411-1)

Docker was updated to version 1.3.1 to fix two security issues and several other bugs. These security issues were fixed : - Prevent fallback to SSL protocols lower than TLS 1.0 for client, daemon and registry CVE-2014-5277. - Secure HTTPS connection to registries with certificate verification and...

MGASA-2014-0410 Updated golang packages fix CVE-2014-7189

Updated golang packages fix security vulnerability: Go 1.1 through 1.3.2 has an issue that affects programs that use crypto/tls to implement a TLS server. If the server enables TLS client authentication using certificates and explicitly sets SessionTicketsDisabled to true in the tls.Config, then ...

FreeBSD : OpenSSL -- multiple vulnerabilities (78cc8a46-3e56-11e1-89b4-001ec9578670)

Vulnerability in OpenSSL - Invalid GOST parameters DoS Attack

A malicious TLS client can send an invalid set of GOST parameters which will cause the server to crash due to lack of error checking. This could be used in a denial-of-service attack. Only users of the OpenSSL GOST ENGINE are affected by this bug. Found by Andrey Kulikov...
