**Name of the Vulnerable Software and Affected Versions**
radare2 versions prior to 5.3.0
**Description**
The issue is related to a double free vulnerability in the pyc parse via a crafted file, which can lead to a denial of service (DoS). This vulnerability can be exploited by a remote attacker, allowing them to cause a service disruption. The vulnerability is associated with the use of memory after it has been freed.
**Recommendations**
