CVE-ID: CVE-2022-3297

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the process_next_cpt_value() function in insexpand.c when processing files. A remote attacker can trick the victim to open a specially crafted flie, trigger a use-after-free error and execute arbitrary code on the system.
