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. For the oldstable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u18. For the stable distribution (jessie), these problems have been fixed in version 1.0.1k-3+deb8u2. For the unstable distribution (sid), these problems have been fixed in version 1.0.2e-1 or earlier. We recommend that you upgrade your openssl packages.
