Multiple vulnerabilities have been discovered in Opera, allowing for the
execution of arbitrary code.
||www-client/opera on all architectures
Opera is a fast web browser that is available free of charge.
Multiple vulnerabilities have been discovered in Opera:
- Opera does not restrict the ability of a framed web page to change
the address associated with a different frame (CVE-2008-4195).
- Chris Weber (Casaba Security) discovered a Cross-site scripting
- Michael A. Puls II discovered
that Opera can produce argument strings that contain uninitialized
memory, when processing custom shortcut and menu commands
- Lars Kleinschmidt discovered that Opera, when
rendering an HTTP page that has loaded an HTTPS page into a frame,
displays a padlock icon and offers a security information dialog
reporting a secure connection (CVE-2008-4198).
- Opera does not
prevent use of links from web pages to feed source files on the local
- Opera does not ensure that the address
field of a news feed represents the feed's actual URL
- Opera does not check the CRL override upon
encountering a certificate that lacks a CRL (CVE-2008-4292).
- Chris (Matasano Security) reported that Opera may crash if it is
redirected by a malicious page to a specially crafted address
- Nate McFeters reported that Opera runs Java
applets in the context of the local machine, if that applet has been
cached and a page can predict the cache path for that applet and load
it from the cache (CVE-2008-4695).
- Roberto Suggi Liverani
(Security-Assessment.com) reported that Opera's History Search results
does not escape certain constructs correctly, allowing for the
injection of scripts into the page (CVE-2008-4696).
Bloom reported that Opera's Fast Forward feature incorrectly executes
scripts from a page held in a frame in the outermost page instead of
Bloom reported that Opera does not block some scripts when previewing a
news feed (CVE-2008-4698).
- Opera does not correctly sanitize
content when certain parameters are passed to Opera's History Search,
allowing scripts to be injected into the History Search results page
- Opera's links panel incorrectly causes
scripts from a page held in a frame to be executed in the outermost
page instead of the page where the URL was located
These vulnerabilties allow remote attackers to execute arbitrary code,
to run scripts injected into Opera's History Search with elevated
privileges, to inject arbitrary web script or HTML into web pages, to
manipulate the address bar, to change Opera's preferences, to determine
the validity of local filenames, to read cache files, browsing history,
and subscribed feeds or to conduct other attacks.
There is no known workaround at this time.
All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.62"
