| Description: | Summary:
The remote host is missing an update for the 'firefox' package(s) announced via the USN-1548-2 advisory.
Vulnerability Insight:
USN-1548-1 fixed vulnerabilities in Firefox. The new package caused a
regression in Private Browsing which could leak sites visited to the
browser cache. This update fixes the problem.
Original advisory details:
Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary, Andrew
Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and Daniel
Holbert discovered memory safety issues affecting Firefox. If the user were
tricked into opening a specially crafted page, an attacker could exploit
these to cause a denial of service via application crash, or potentially
execute code with the privileges of the user invoking Firefox.
(CVE-2012-1970, CVE-2012-1971)
Abhishek Arya discovered multiple use-after-free vulnerabilities. If the
user were tricked into opening a specially crafted page, an attacker could
exploit these to cause a denial of service via application crash, or
potentially execute code with the privileges of the user invoking Firefox.
(CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976,
CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960,
CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)
Mariusz Mlynsk discovered that it is possible to shadow the location object
using Object.defineProperty. This could potentially result in a cross-site
scripting (XSS) attack against plugins. With cross-site scripting
vulnerabilities, if a user were tricked into viewing a specially crafted
page, a remote attacker could exploit this to modify the contents or steal
confidential data within the same domain. (CVE-2012-1956)
Mariusz Mlynski discovered an escalation of privilege vulnerability through
about:newtab. This could possibly lead to potentially code execution with
the privileges of the user invoking Firefox. (CVE-2012-3965)
Frederic Hoguin discovered that bitmap format images with a negative height
could potentially result in memory corruption. If the user were tricked
into opening a specially crafted image, an attacker could exploit
this to cause a denial of service via application crash, or potentially
execute code with the privileges of the user invoking Firefox.
(CVE-2012-3966)
It was discovered that Firefox's WebGL implementation was vulnerable to
multiple memory safety issues. If the user were tricked into opening a
specially crafted page, an attacker could exploit these to cause a denial
of service via application crash, or potentially execute code with the
privileges of the user invoking Firefox. (CVE-2012-3967, CVE-2012-3968)
Arthur Gerkis discovered multiple memory safety issues in Firefox's
Scalable Vector Graphics (SVG) implementation. If the user were tricked
into opening a specially crafted image, an attacker could exploit these to
cause a denial of service via application crash, or potentially execute
code with the privileges of the user invoking ... [Please see the references for more information on the vulnerabilities]
