Description

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 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-2015-3194). Adam Langley of Google/BoringSSL discovered that OpenSSL will leak memory when presented with a malformed X509_ATTRIBUTE structure (CVE-2015-3195). A race condition flaw in the handling of PSK identify hints was discovered, potentially leading to a double free of the identify hint data (CVE-2015-3196).
