Descripción
*** Pendiente de traducción *** GNU patch is vulnerable to a denial of service (DoS) due to improper validation of hunk (single block of changes in diff) line offsets in unified-diff input. A specially crafted patch can specify an extremely large line number, causing the application to enter an effectively infinite processing loop while attempting to locate the requested position.<br />
This results in excessive CPU consumption and prevents the process from completing.<br />
An attacker can trigger this behavior by supplying a malicious patch file, causing the utility to become unresponsive and require manual termination.<br />
<br />

This issue has been fixed in the commit faba04ef4f2b410257f76c1b9dc85e350929c4b9
