Pronađeni su i otklonjeni brojni propusti paketa Mozilla XULRunner i Firefox. Ovi nedostaci mogli su omogućiti zlonamjernom korisniku da ugrozi komunikaciju između preglednika i poslužitelja, pokrene proizvoljni programski kod te izvede DoS napad.
Paket:
Firefox 11.x, Xulrunner 10.x
Operacijski sustavi:
openSUSE 12.1
Kritičnost:
9.3
Problem:
korupcija memorije, pogreška u programskoj funkciji, pogreška u programskoj komponenti, XSS
Većina od 18 propusta nalaze se u funkcijama "nsDocument::AdoptNode", "ElementAnimations::EnsureStyleRuleFor", "nsGlobalWindow::PageHidden" itd. Neki od propusta se javljaju zbog nepravilnog interpretiranja javascript sadržaja, pogrešaka u radu mehanizma za pretraživanje te neodgovarajućeg rukovanja prilikom ručnog postavljanja tabova.
Posljedica:
Zlonamjerni korisnik mogao je iskoristiti ove propuste za proizvoljno izvođenje koda ili gašenje programa, te za dobivanje nedozvoljenih informacija kao i do ugrožavanja komunikacije između preglednika i poslužitelja.
Rješenje:
Preporuča se nadogradnja paketa na zadnju inačicu.

Description:
Mozilla XULRunner was updated to 14.0.1, fixing bugs and
security issues:
Following security issues were fixed: MFSA 2012-42: 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-2012-1949: Brian Smith, Gary Kwong, Christian Holler,
Jesse Ruderman, Christoph Diehl, Chris Jones, Brad Lassey,
and Kyle Huey reported memory safety problems and crashes
that affect Firefox 13.
CVE-2012-1948: Benoit Jacob, Jesse Ruderman, Christian
Holler, and Bill McCloskey reported memory safety problems
and crashes that affect Firefox ESR 10 and Firefox 13.
MFSA 2012-43 / CVE-2012-1950: Security researcher Mario
Gomes andresearch firm Code Audit Labs reported a mechanism
to short-circuit page loads through drag and drop to the
addressbar by canceling the page load. This causes the
address of the previously site entered to be displayed in
the addressbar instead of the currently loaded page. This
could lead to potential phishing attacks on users.
MFSA 2012-44
Google security researcher Abhishek Arya used the Address
Sanitizer tool to uncover four issues: two use-after-free
problems, one out of bounds read bug, and a bad cast. The
first use-after-free problem is caused when an array of
nsSMILTimeValueSpec objects is destroyed but attempts are
made to call into objects in this array later. The second
use-after-free problem is in nsDocument::AdoptNode when it
adopts into an empty document and then adopts into another
document, emptying the first one. The heap buffer overflow
is in ElementAnimations when data is read off of end of an
array and then pointers are dereferenced. The bad cast
happens when nsTableFrame::InsertFrames is called with
frames in aFrameList that are a mix of row group frames and
column group frames. AppendFrames is not able to handle
this mix.
All four of these issues are potentially exploitable.
CVE-2012-1951: Heap-use-after-free in
nsSMILTimeValueSpec::IsEventBased CVE-2012-1954:
Heap-use-after-free in nsDocument::AdoptNode CVE-2012-1953:
Out of bounds read in ElementAnimations::EnsureStyleRuleFor
CVE-2012-1952: Bad cast in nsTableFrame::InsertFrames
MFSA 2012-45 / CVE-2012-1955: Security researcher Mariusz
Mlynski reported an issue with spoofing of the location
property. In this issue, calls to history.forward and
history.back are used to navigate to a site while
displaying the previous site in the addressbar but changing
the baseURI to the newer site. This can be used for
phishing by allowing the user input form or other data on
the newer, attacking, site while appearing to be on the
older, displayed site.
MFSA 2012-46 / CVE-2012-1966: Mozilla security researcher
moz_bug_r_a4 reported a cross-site scripting (XSS) attack
through the context menu using a data: URL. In this issue,
context menu functionality ("View Image", "Show only this
frame", and "View background image") are disallowed in a
javascript: URL but allowed in a data: URL, allowing for
XSS. This can lead to arbitrary code execution.
MFSA 2012-47 / CVE-2012-1957: Security researcher Mario
Heiderich reported that javascript could be executed in the
HTML feed-view using tag within the RSS . This problem is
due to tags not being filtered out during parsing and can
lead to a potential cross-site scripting (XSS) attack. The
flaw existed in a parser utility class and could affect
other parts of the browser or add-ons which rely on that
class to sanitize untrusted input.
MFSA 2012-48 / CVE-2012-1958: Security researcher Arthur
Gerkis used the Address Sanitizer tool to find a
use-after-free in nsGlobalWindow::PageHidden when
mFocusedContent is released and oldFocusedContent is used
afterwards. This use-after-free could possibly allow for
remote code execution.
MFSA 2012-49 / CVE-2012-1959: Mozilla developer Bobby
Holley found that same-compartment security wrappers (SCSW)
can be bypassed by passing them to another compartment.
Cross-compartment wrappers often do not go through SCSW,
but have a filtering policy built into them. When an object
is wrapped cross-compartment, the SCSW is stripped off and,
when the object is read read back, it is not known that
SCSW was previously present, resulting in a bypassing of
SCSW. This could result in untrusted content having access
to the XBL that implements browser functionality.
MFSA 2012-50 / CVE-2012-1960: Google developer Tony Payne
reported an out of bounds (OOB) read in QCMS, Mozillaâ??s
color management library. With a carefully crafted color
profile portions of a user's memory could be incorporated
into a transformed image and possibly deciphered.
