Also known as:GHSA-29xx-hcv2-c4cpALPINE-CVE-2023-0216CGA-8w7j-4g85-46jgRUSTSEC-2023-0011

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.
