CVE-2023-0216
The result of the dereference is an application crash which could lead to a denial of service attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
