Detailsinfo

A vulnerability was found in OpenSSL up to 3.0.7 (Network Encryption Software). It has been declared as problematic. This vulnerability affects the function d2i_PKCS7/d2i_PKCS7_bio/d2i_PKCS7_fp. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. CVE summarizes:

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.

The weakness was shared 02/07/2023 by Marc Schönefeld. This vulnerability was named CVE-2023-0216. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 211573 (Oracle Linux 9 : openssl / and / openssl-fips-provider (ELSA-2024-9333)), which helps to determine the existence of the flaw in a target environment.
