Name of the Vulnerable Software and Affected Versions PHP versions prior to 5.3.4

Description A race condition exists in the PCNTL extension when a user-defined signal handler is present, potentially allowing attackers to cause a denial of service through memory corruption by sending a large number of concurrent signals.

Recommendations For versions prior to 5.3.4, update to version 5.3.4 or later to resolve the issue. As a temporary workaround, consider disabling the PCNTL extension until a patch is available. Restrict access to signal handlers to minimize the risk of exploitation.
