DESCRIPTION:
Some vulnerabilities have been reported in Opera, which can be
exploited by malicious people to conduct spoofing and
cross-site
scripting attacks, bypass certain security restrictions,
disclose
potentially sensitive information, or potentially compromise a
user's
system.
1) An unspecified error exists when Opera is executed as a
protocol
handler. This can be exploited to cause a crash and potentially
execute arbitrary code.
NOTE: Reportedly, the vulnerability only affects Opera for
Windows.
2) The problem is that a web page can change the address of
frames
from other sites opened inside a pop-up window. This can be
exploited
to load malicious content into a frame of a trusted website.
3) An unspecified error can be exploited to conduct cross-site
scripting attacks. No further information is currently
available.
4) An error exists in the processing of custom shortcut and
menu
commands. This can be exploited to execute applications with
potentially dangerous parameters, created from uninitialized
memory.
Successful exploitation may allow execution of arbitrary code,
but
requires that a user is tricked into modifying shortcuts or
menu
files.
5) An error exists while reporting websites as secure for
browsing.
This can be exploited to determine the reporting of an insecure
website as secure by including a frame with content from a
secure
website.
6) An error exists when checking if a web page links to a local
file.
This can be exploited to link to local feed source files and
potentially determine if a file is present on the local system.
7) An error exists when processing news feed subscription
requests.
This can be exploited to change the address field to the
address of
the malicious web page and mislead a user.
The vulnerabilities are reported in versions prior to 9.52.
SOLUTION:
Update to version 9.52.
