openssl is vulnerable to Unchecked Return Value to NULL Pointer Dereference
20
Low Risk
This Affects:
opensslTL;DR
Affected versions of this package are vulnerable to a Denial-of-Service (DoS) attack due to an API behavior change in OpenSSL 3.0, where the EVP_PKEY_get0() function can now return NULL, a case that was not possible in OpenSSL versions 1.1.1 and earlier. If an application does not implement a NULL check after this function call, an attacker could potentially provide a malformed or invalid key, causing the application to dereference a NULL pointer and crash.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
openssl is vulnerable to Unchecked Return Value to NULL Pointer Dereference in versions 3.3.0 - 3.3.1, 3.2.0 - 3.2.2 and 3.0.0 - 3.1.2.
How to fix this
Upgrade the openssl library to the patch version.
