None · Pgpdump · CVE-2016-4021
**Name of the Vulnerable Software and Affected Versions**
pgpdump versions prior to 0.30
**Description**
The issue allows context-dependent attackers to cause a denial of service, resulting in an infinite loop and CPU consumption, via crafted input. This is demonstrated by the string `xa3x03`.
**Recommendations**
For versions prior to 0.30, update to version 0.30 or later to resolve the issue. As a temporary workaround, consider restricting the input to the `read binary` function to prevent crafted input from causing a denial of service.
