| From the Mandriva advisory:
Security researcher regenrecht reported (via TippingPoint's Zero Day
Initiative) a potential reuse of a deleted image frame in Firefox 3.6's
handling of multipart/x-mixed-replace images. Although no exploit was
shown, re-use of freed memory has led to exploitable vulnerabilities
in the past (CVE-2010-0164).
Mozilla developers identified and fixed several stability bugs in the
browser engine used in Firefox and other Mozilla-based products. Some
of these crashes 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-2010-0165,
CVE-2010-0167).
Mozilla developer Josh Soref of Nokia reported that documents
failed to call certain security checks when attempting to preload
images. Although the image content is not available to the page, it
is possible to specify protocols that are normally not allowed in a
web page such as file:. This includes internal schemes implemented
by add-ons that might perform privileged actions resulting in
something like a Cross-Site Request Forgery (CSRF) attack against
the add-on. Potential severity would depend on the add-ons installed
(CVE-2010-0168).
Mozilla developer Blake Kaplan reported that the window.location object
was made a normal overridable JavaScript object in the Firefox 3.6
browser engine (Gecko 1.9.2) because new mechanisms were developed
to enforce the same-origin policy between windows and frames. This
object is unfortunately also used by some plugins to determine the page
origin used for access restrictions. A malicious page could override
this object to fool a plugin into granting access to data on another
site or the local file system. The behavior of older Firefox versions
has been restored (CVE-2010-0170).
Unspecified vulnerability in Mozilla Firefox 3.5.x through 3.5.8 allows
remote attackers to cause a denial of service (memory corruption and
application crash) and possibly have unknown other impact via vectors
that might involve compressed data, a different vulnerability than
CVE-2010-1028 (CVE-2010-1122).
