Description
A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2
ciphers that have been disabled on the server. This could result in weak
SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to
man-in-the-middle attacks. (CVE-2015-3197)
A side-channel attack was found that makes use of cache-bank conflicts on
the Intel Sandy-Bridge microarchitecture. An attacker who has the ability
to control code in a thread running on the same hyper-threaded core as the
victim's thread that is performing decryption, could use this flaw to
recover RSA private keys. (CVE-2016-0702)
A double-free flaw was found in the way OpenSSL parsed certain malformed
DSA (Digital Signature Algorithm) private keys. An attacker could create
specially crafted DSA private keys that, when processed by an application
compiled against OpenSSL, could cause the application to crash.
(CVE-2016-0705)
An integer overflow flaw, leading to a NULL pointer dereference or a
heap-based memory corruption, was found in the way some BIGNUM functions of
OpenSSL were implemented. Applications that use these functions with large
untrusted input could crash or, potentially, execute arbitrary code.
(CVE-2016-0797)
