Description

An invalid pointer dereference on read can be triggered when an

application tries to load malformed PKCS7 data with the

d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions.

The result of the dereference is an application crash which could

lead to a denial of service attack. The TLS implementation in OpenSSL

does not call this function however third party applications might

call these functions on untrusted data.
