SSL: OpenSSL Invalid PSS Parameters Denial of Service

This signature detects attempts to exploit a known vulnerability against OpenSSL while performing signature algorithm extension communication. A successful attack can result in a denial-of-service condition.

Extended Description

The ASN.1 signature-verification implementation in the rsa_item_verify function in crypto/rsa/rsa_ameth.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted RSA PSS parameters to an endpoint that uses the certificate-verification feature.
