CVE-2023-0216

CVE-2023-0216: openssl-src subject to Invalid pointer dereference in `d2i_PKCS7` functions

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.

Root Cause Analysis

All vulnerability sources explicitly name d2i_PKCS7/d2i_PKCS7_bio/d2i_PKCS7_fp as the entry points
The CWE-476 classification indicates NULL pointer dereference during data parsing
The OpenSSL commit shows fixes in PKCS7 handling code
Advisories specify these functions process untrusted PKCS7 data without proper validation
Crash occurs during decoding of malformed structures, which these functions directly handle
