タイプ/重大度

Security Advisory: Critical

トピック

Updated firefox packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

説明

Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.

A web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2012-1970, CVE-2012-1972, CVE-2012-1973, CVE-2012-1974,
CVE-2012-1975, CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958,
CVE-2012-3959, CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963,
CVE-2012-3964)

A web page containing a malicious Scalable Vector Graphics (SVG) image file
could cause Firefox to crash or, potentially, execute arbitrary code with
the privileges of the user running Firefox. (CVE-2012-3969, CVE-2012-3970)

Two flaws were found in the way Firefox rendered certain images using
WebGL. A web page containing malicious content could cause Firefox to crash
or, under certain conditions, possibly execute arbitrary code with the
privileges of the user running Firefox. (CVE-2012-3967, CVE-2012-3968)

A flaw was found in the way Firefox decoded embedded bitmap images in Icon
Format (ICO) files. A web page containing a malicious ICO file could cause
Firefox to crash or, under certain conditions, possibly execute arbitrary
code with the privileges of the user running Firefox. (CVE-2012-3966)

A flaw was found in the way the "eval" command was handled by the Firefox
Web Console. Running "eval" in the Web Console while viewing a web page
containing malicious content could possibly cause Firefox to execute
arbitrary code with the privileges of the user running Firefox.
(CVE-2012-3980)

An out-of-bounds memory read flaw was found in the way Firefox used the
format-number feature of XSLT (Extensible Stylesheet Language
Transformations). A web page containing malicious content could possibly
cause an information leak, or cause Firefox to crash. (CVE-2012-3972)

It was found that the SSL certificate information for a previously visited
site could be displayed in the address bar while the main window displayed
a new page. This could lead to phishing attacks as attackers could use this
flaw to trick users into believing they are viewing a trusted site.
(CVE-2012-3976)

A flaw was found in the location object implementation in Firefox.
Malicious content could use this flaw to possibly allow restricted content
to be loaded. (CVE-2012-3978)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.7 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Gary Kwong, Christian Holler, Jesse Ruderman, John
Schoenick, Vladimir Vukicevic, Daniel Holbert, Abhishek Arya, Frederic
Hoguin, miaubiz, Arthur Gerkis, Nicolas Gregoire, Mark Poticha,
moz_bug_r_a4, and Colby Russell as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 10.0.7 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
