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

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
