NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl-libs package and not the openssl-libs package as distributed by AlmaLinux.
See How to fix? for AlmaLinux: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.
