NSS -- MD5 downgrade in TLS 1.2 signatures

The Mozilla Project reports: Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services NSS where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the acceptin...

MD5 signatures accepted within TLS 1.2 ServerKeyExchange in server signature — Mozilla

Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services NSS where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the accepting MD5 as a hash algorithm in...

USN-2830-1: OpenSSL vulnerabilities

Guy Leaver discovered that OpenSSL incorrectly handled a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only applied to Ubuntu 15.10...

OpenSSL 1.0.0 < 1.0.0t Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.0t. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.0t advisory. - ssl/s3clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client,...

CVE-2015-3196

ssl/s3clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client, writes the PSK identity hint to an incorrect data structure, which allows remote servers to cause a denial of service race condition and double free via a crafted...

OpenSSL ServerKeyExchange Message Handling Remote Denial of Service Vulnerability

OpenSSL is an open source implementation of SSL for strong encryption of network communications. A security vulnerability exists in OpenSSL, where a remote attacker submitting a special anonymous DH encryption suite of ServerKeyExchange messages can crash the target service if the p-value is set ...

Updated openssl packages fix security vulnerability

If a client receives a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0 then a seg fault can occur leading to a possible denial of service attack CVE-2015-1794. Loic Jonas Etienne of Qnective AG discovered that the signature verification routines will crash with a NU...
