DESCRIPTION:
A vulnerability has been reported in CGI.pm, which can be exploited
by malicious people to conduct HTTP response splitting attacks in an
application using the library.

The vulnerability is caused due to an error in the "multipart_init()"
function when handing a message with "multipart/x-mixed-replace" mime
type. This can be exploited to include arbitrary HTTP headers in a
response sent to the user.

The vulnerability is reported in versions prior to 3.50.

SOLUTION:
Update to version 3.50.

PROVIDED AND/OR DISCOVERED BY:
