**Name of the Vulnerable Software and Affected Versions** Radare2 (affected versions not specified) **Description** The issue is related to a division by zero vulnerability in the Mach-O parser's rebase buffer function. This vulnerability allows attackers to create malicious inputs that can cause a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Radare2 (affected versions not specified) **Description** The issue is related to a use-after-free vulnerability in the pyc parser's get none object function. This allows an attacker to read freed memory, potentially causing a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**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** For versions prior to 5.3.0, update to version 5.3.0 or later to resolve the issue. As a temporary workaround, consider restricting access to crafted files that could trigger the double free vulnerability in the pyc parse. Avoid using the pyc parse function with untrusted files until the issue is resolved.
