CWE-476  (opens in a new tab)

How to fix?

Upgrade RHEL:9 openssl to version 1:3.0.1-47.el9_1 or higher.
This issue was patched in RHSA-2023:0946.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
