OVERVIEW
Many vulnerabilities have been fixed in Mozilla Firefox and
Thunderbird and in SeaMonkey.[1,2,3,4,5,6,7,8]
IMPACT
The vendor has provided the following details about the vulnerabilities:
"Security researchers Blair Strang and Scott Bell of Security Assessment
found that when a parent window spawns and closes a child window that
uses the file open dialog, a crash can be induced in shlwapi.dll on
32-bit Windows 7 systems. This crash may be potentially exploitable." [1]
"Firefox prevents the dropping of javascript: links onto a frame to
prevent malicious sites from tricking users into performing a cross-site
scripting (XSS) attacks on themselves. Security researcher Soroush
Dalili reported a way to bypass this protection." [2]
"Security researcher Atte Kettunen from OUSPG found two issues with
Firefox's handling of SVG using the Address Sanitizer tool. The first
issue, critically rated, is a use-after-free in SVG animation that
could potentially lead to arbitrary code execution. The second issue
is rated moderate and is an out of bounds read in SVG Filters. This
could potentially incorporate data from the user's memory, making it
accessible to the page content." [3]
"Security Researcher Mike Brooks of Sitewatch reported that if multiple
Content Security Policy (CSP) headers are present on a page, they have
an additive effect page policy. Using carriage return line feed (CRLF)
injection, a new CSP rule can be introduced which allows for cross-site
scripting (XSS) on sites with a separate header injection vulnerability." [4]
"Security researcher Mariusz Mlynski reported that an attacker able to
convince a potential victim to set a new home page by dragging a link
to the "home" button can set that user's home page to a javascript:
URL. Once this is done the attacker's page can cause repeated crashes
of the browser, eventually getting the script URL loaded in the
privileged about:sessionrestore context." [5]
"Mozilla community member Daniel Glazman of Disruptive Innovations
reported a crash when accessing a keyframe's cssText after dynamic
modification. This crash may be potentially exploitable." [6]
"Mozilla developer Matt Brubeck reported that window.fullScreen is
writeable by untrusted content now that the DOM fullscreen API is
enabled. Because window.fullScreen does not include mozRequestFullscreen's
security protections, it could be used for UI spoofing. This code
change makes window.fullScreen read only by untrusted content, forcing
the use of the DOM fullscreen API in normal usage." [7]
"Mozilla developers identified and fixed several memory safety bugs in
the browser engine used in Firefox and other Mozilla-based products.
Some of these bugs showed evidence of memory corruption under certain
circumstances, and we presume that with enough effort at least some of
these could be exploited to run arbitrary code.
In general these flaws cannot be exploited through email in the
Thunderbird and SeaMonkey products because scripting is disabled, but
are potentially a risk in browser or browser-like contexts in those
products." [8]
MITIGATION
Users of the affected versions should upgrade to the latest versions:
- Firefox: 11, 10.0.3, or 3.6.28
- Thunderbird: 11, 10.0.3, or 3.1.20
- SeaMonkey: 2.8
