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.
