DESCRIPTION:
Multiple vulnerabilities have been reported in Symantec Web Gateway,
which can be exploited by malicious people to disclose potentially
sensitive information, conduct cross-site scripting attacks,
manipulate certain data, and compromise a vulnerable system.

1) An unspecified error can be exploited to inject arbitrary
commands. No further information is currently available.

2) Certain unspecified input is not properly verified before being
used to include files. This can be exploited to include arbitrary
files from local or external resources.

3) Certain unspecified input is not properly verified before being
used to download or delete arbitrary files. This can be exploited to
remove or disclose the contents of arbitrary files.

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

The vulnerabilities are reported in versions prior to 5.0.3.

SOLUTION:
Update to version 5.0.3.

PROVIDED AND/OR DISCOVERED BY:
