Last modified Jun 17, 2026

CVE-2023-0216 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 1.85% chance of exploitation in the next 30 days.
