Description

Multiple vulnerabilities have been discovered in OpenSSL, a Secure Sockets Layer toolkit. The Common Vulnerabilities and Exposures project identifies the following issues:

CVE-2015-3194 Loic Jonas Etienne of Qnective AG discovered that the signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. A remote attacker can exploit this flaw to crash any certificate verification operation and mount a denial of service attack.

CVE-2015-3195 Adam Langley of Google/BoringSSL discovered that OpenSSL will leak memory when presented with a malformed X509_ATTRIBUTE structure.

CVE-2015-3196 A race condition flaw in the handling of PSK identify hints was discovered, potentially leading to a double free of the identify hint data.
