An invalid pointer use flaw was found in OpenSSL’s ASN1_TYPE_cmp() function. With a specially crafted X.509 certificate that had been verified by the application, a remote attacker could crash a TLS/SSL client or server using OpenSSL.
The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check certificate signature algorithm consistency this can be used to crash any certificate verification operation and exploited in a denial of service attack. Any application which performs certificate verification is vulnerable, including OpenSSL clients and servers which enable client authentication.
