Description

A flaw was found in OpenSSL. An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVP_PKEY_public_check() function, most likely leading to an application crash. This function can be called on public keys supplied from untrusted sources, which could allow an attacker to cause a denial of service.
