Description

CVE-2023-0465 affecting package openssl for versions less than 1.1.1k-23

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability none.
