CVE-2023-0216: Invalid pointer dereference in d2i_PKCS7 functions

First published: Wed Jan 25 2023(Updated: )

A flaw was found in OpenSSL. 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. This may result in an application crash which could lead to a denial of service. The TLS implementation in OpenSSL does not call this function, however, third party applications might call these functions on untrusted data.
