**Name of the Vulnerable Software and Affected Versions** Exim (affected versions not specified) **Description** A vulnerability was found in Exim, affecting the Regex Handler component. This issue leads to use after free, potentially allowing a remote attacker to cause a denial of service or gain access to confidential data. The manipulation of the Regex Handler component can be exploited by a remote attacker, allowing them to send a special request to the application and obtain access to sensitive information. **Recommendations** To fix this issue, it is recommended to apply a patch with the name 4e9ed49f8f12eb331b29bd5b6dc3693c520fddc2. As a temporary workaround, consider disabling the Regex Handler component until a patch is available. Restrict access to the component to minimize the risk of exploitation. Avoid using the component in a way that could lead to use after free until the issue is resolved.
