CVE-2023-0465 Open this link in a new tabHow to fix?
Upgrade AlmaLinux:9 openssl to version 1:3.0.7-16.el9_2 or higher.
This issue was patched in ALSA-2023:3722.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks.
Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether.
Policy processing is disabled by default but can be enabled by passing
the -policy' argument to the command line utilities or by calling the X509_VERIFY_PARAM_set1_policies()' function.
