Description
A flaw was found in OpenSSL. This type confusion vulnerability allows a remote attacker to cause a denial of service (DoS) by providing specially crafted PKCS#7 data to an application that performs signature verification. The vulnerability occurs because the application accesses an ASN1_TYPE union member without proper type validation, leading to an invalid or NULL pointer dereference and a crash.
