NVD Description

Note: Versions mentioned in the description apply only to the upstream yara package and not the yara package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

An invalid pointer release vulnerability exists in YARA 4.5.8 during deserialization of compiled .yrc rule files. The vulnerability is caused by insufficient validation of external-variable pointers, which may lead to invalid free in yr_rules_destroy() or wild pointer access in yr_object_create(). An attacker can provide a specially crafted .yrc file that causes memory corruption and application crash.
