Description
A flaw was found in perl-cgi. A remote attacker can trigger a Denial of Service (DoS) by supplying a crafted request parameter processed by the uploadInfo function. Because the function fails to verify that the parameter represents an upload file handle, the invalid input causes an unhandled exception that terminates the application process.
