Synopsis
The remote Ubuntu host is missing a security-related patch.Description
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.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 Firefox.
(CVE-2012-3969, CVE-2012-3970)
Christoph Diehl discovered multiple memory safety issues in the bundled Graphite 2 library. 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-2012-3971)
Nicolas Gregoire discovered an out-of-bounds read in the format-number feature of XSLT. This could potentially cause inaccurate formatting of numbers and information leakage.
(CVE-2012-3972)
Mark Goodwin discovered that under certain circumstances, Firefox's developer tools could allow remote debugging even when disabled. (CVE-2012-3973)
It was discovered that when the DOMParser is used to parse text/html data in a Firefox extension, linked resources within this HTML data will be loaded. If the data being parsed in the extension is untrusted, it could lead to information leakage and potentially be combined with other attacks to become exploitable. (CVE-2012-3975)
Mark Poticha discovered that under certain circumstances incorrect SSL certificate information can be displayed on the addressbar, showing the SSL data for a previous site while another has been loaded. This could potentially be used for phishing attacks. (CVE-2012-3976)
It was discovered that, in some instances, certain security checks in the location object could be bypassed. This could allow for the loading of restricted content and can potentially be combined with other issues to become exploitable. (CVE-2012-3978)
Colby Russell discovered that eval in the web console can execute injected code with chrome privileges, leading to the running of malicious code in a privileged context. If the user were tricked into opening a specially crafted page, 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-2012-3980).
