The remote host is missing an update to mozilla
announced via advisory MDVSA-2012:032.
Security issues were identified and fixed in mozilla firefox and
thunderbird:
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
(CVE-2012-0454).
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
(CVE-2012-0455).
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 (CVE-2012-0457, CVE-2012-0456).
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 (CVE-2012-0451).
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 (CVE-2012-0458).
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
(CVE-2012-0459).
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 (CVE-2012-0460).
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
(CVE-2012-0461, CVE-2012-0462, CVE-2012-0464).
The mozilla firefox and thunderbird packages has been upgraded to the
latest respective versions which is unaffected by these security flaws.
Additionally the NSS and NSPR packages has been upgraded to the latest
versions. The OpenJDK java plugin (icedtea-web) has been upgraded to
the 1.1.5 version whish bas better support for firefox 10.x+.
Affected: 2011.
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
