DESCRIPTION:
A vulnerability and some security issues have been reported in Opera,
which can be exploited by malicious people to bypass certain security
restrictions or compromise a user's system.

1) The problem is that the "Download" dialog provides the option to
run a downloadable executable at a predictable location in the
browser window. This can be exploited to trick a user into clicking
on the "Run" button by positioning a new window on top of the
"Download" dialog that is closed e.g. via a timeout shortly before
the user clicks on a link within this window.

This security issue is confirmed in version 10.53, 10.54, and 10.60
on Windows XP. Other versions may also be affected.

NOTE: This is related to SA15781.

2) An error exists in the processing of painting operations on a
canvas while certain transformations are being applied, which can be
exploited to cause a heap-based buffer overflow.

Successful exploitation may allow execution of arbitrary code.

3) An input sanitisation error in the handling of news feed previews
can be exploited to execute script code and automatically subscribe
the user to the feed.

SOLUTION:
Update to version 10.61.
