DESCRIPTION:
A vulnerability has been reported in cURL, which can be exploited by
malicious people to compromise a user's system.

The vulnerability is caused by an error in the "parse_filename()"
function within src/main.c when stripping directory separators from
the "Content-Disposition" HTTP header and can be exploited to
overwrite files via a specially crafted server response.

Successful exploitation requires cURL to be invoked with the
"-J/--remote-header-name" option on platforms which support the
backslash ("\") directory separator (e.g. Windows, Netware, MSDOS,
OS/2, and Symbian).

NOTE: The "libcurl" library is not affected.

The vulnerability is reported in versions 7.20.0 through 7.21.1.

SOLUTION:
Update to version 7.21.2.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Dan Fandrich.
