MGASA-2016-0169 Updated openssl packages fix security vulnerability

An overflow can occur in the EVPEncodeUpdate function which is used for Base64 encoding of binary data. If an attacker is able to supply very large amounts of input data then a length check can overflow resulting in a heap corruption CVE-2016-2105. An overflow can occur in the EVPEncryptUpdate...

Design/Logic Flaw

The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability...
