1) Problem Description and Brief Discussion
The Mozilla Firefox web browser was updated to security update version
1.5.0.10 on older products and Mozilla Firefox to version 2.0.0.2 on
openSUSE 10.2 to fix various security issues.
Updates for the Mozilla seamonkey suite before 10.2, Mozilla Suite
and Mozilla Thunderbird are still pending.
Full details can be found on:
https://www.mozilla.org/en-US/security/known-vulnerabilities/
- MFSA 2007-01: As part of the Firefox 2.0.0.2 and 1.5.0.10 update
releases several bugs were fixed to improve the stability of the
browser. Some of these were crashes that showed evidence of memory
corruption and we presume that with enough effort at least some of
these could be exploited to run arbitrary code. These fixes affected
the layout engine (CVE-2007-0775), SVG renderer (CVE-2007-0776)
and javascript engine (CVE-2007-0777).
- MFSA 2007-02: Various enhancements were done to make XSS exploits
against websites less effective. These included fixes for invalid
trailing characters (CVE-2007-0995), child frame character set
inheritance (CVE-2007-0996), password form injection (CVE-2006-6077),
and the Adobe Reader universal XSS problem.
- MFSA 2007-03/CVE-2007-0778: AAd reported a potential disk cache
collision that could be exploited by remote attackers to steal
confidential data or execute code.
- MFSA 2007-04/CVE-2007-0779: David Eckel reported that browser UI
elements--such as the host name and security indicators--could be
spoofed by using a large, mostly transparent, custom cursor and
adjusting the CSS3 hot-spot property so that the visible part of
the cursor floated outside the browser content area.
- MFSA 2007-05: Manually opening blocked popups could be exploited by
remote attackers to allow XSS attacks (CVE-2007-0780) or to execute
code in local files (CVE-2007-0800).
- MFSA 2007-06:
Two buffer overflows were found in the NSS handling of Mozilla.
CVE-2007-0008: SSL clients such as Firefox and Thunderbird can suffer
a buffer overflow if a malicious server presents a certificate
with a public key that is too small to encrypt the entire "Master
Secret". Exploiting this overflow appears to be unreliable but
possible if the SSLv2 protocol is enabled.
CVE-2007-0009: Servers that use NSS for the SSLv2 protocol can
be exploited by a client that presents a "Client Master Key" with
invalid length values in any of several fields that are used without
adequate error checking. This can lead to a buffer overflow that
presumably could be exploitable.
- MFSA 2007-06/CVE-2007-0981: Michal Zalewski demonstrated that setting
location.hostname to a value with embedded null characters can
confuse the browsers domain checks. Setting the value triggers a
load, but the networking software reads the hostname only up to
the null character while other checks for "parent domain" start at
the right and so can have a completely different idea of what the
current host is.
- MFSA 2007-08/CVE-2007-1092: Michal Zalewski reported a memory
corruption vulnerability in Firefox 2.0.0.1 involving mixing
the onUnload event handler and self-modifying document.write()
calls. This flaw was introduced in Firefox 2.0.0.1 and 1.5.0.9 and
does not affect earlier versions; it is fixed in Firefox 2.0.0.2
and 1.5.0.10.
- MFSA 2007-09/CVE-2007-0994: moz_bug_r_a4 reports that the fix for
MFSA 2006-72 in Firefox 1.5.0.9 and Firefox 2.0.0.1 introduced a
regression that allows scripts from web content to execute arbitrary
code by setting the src attribute of an IMG tag to a specially
crafted javascript: URI.
The same regression also caused javascript: URIs in IMG tags to be
executed even if JavaScript execution was disabled in the global
preferences. This facet was noted by moz_bug_r_a4 and reported
independently by Anbo Motohiko.
2) Solution or Work-Around
There is no known workaround, please install the update packages.
3) Special Instructions and Notes
Please close and restart all running instances of Firefox after the update.
4) Package Location and Checksums
The preferred method for installing security updates is to use the YaST
Online Update (YOU) tool. YOU detects which updates are required and
automatically performs the necessary steps to verify and install them.
Alternatively, download the update packages for your distribution manually
and verify their integrity by the methods listed in Section 6 of this
announcement. Then install the packages using the command
rpm -Fhv
