DESCRIPTION:
Some vulnerabilities have been reported in Palm WebOS, which can be
exploited by malicious people to conduct cross-site scripting attacks
and bypass certain security restrictions.

1) Certain unspecified input is not properly sanitised by the Email
application before being returned to the user. This can be exploited
to execute arbitrary HTML and script code in a user's browser session
in the context of the affected device.

2) An unspecified error can be exploited by Plug-in Development Kit
(PDK) applications to gain write access to the file system and
overwrite arbitrary files.

Successful exploitation of this vulnerability may allow execution of
arbitrary code, but requires tricking a user into installing a
malicious application.

The vulnerabilities are reported in versions 1.4.5 and 1.4.5.1.

SOLUTION:
Upgrade to version 2.1 or later available via the wireless carrier.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits David Belcher, BlackBerry Security Research
Group.
2) Reported by the vendor.
