Vulnerability Insight:
Bob Clary, Christian Holler, Brian Hackett, Bobby Holley, Gary Kwong,
Hilary Hall, Honza Bambas, Jesse Ruderman, Julian Seward, and Olli Pettay
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-2012-0467,
CVE-2012-0468)
Aki Helin discovered a use-after-free vulnerability in XPConnect. An
attacker could potentially exploit this to execute arbitrary code with the
privileges of the user invoking Firefox. (CVE-2012-0469)
Atte Kettunen discovered that invalid frees cause heap corruption in
gfxImageSurface. If a user were tricked into opening a malicious Scalable
Vector Graphics (SVG) image file, 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-2012-0470)
Anne van Kesteren discovered a potential cross-site scripting (XSS)
vulnerability via multibyte content processing errors. 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-2012-0471)
Matias Juntunen discovered a vulnerability in Firefox's WebGL
implementation that potentially allows the reading of illegal video memory.
An attacker could possibly exploit this to cause a denial of service via
application crash. (CVE-2012-0473)
Jordi Chancel, Eddy Bordi, and Chris McGowen discovered that Firefox
allowed the address bar to display a different website than the one the
user was visiting. This could potentially leave the user vulnerable to
cross-site scripting (XSS) attacks. 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-2012-0474)
Simone Fabiano discovered that Firefox did not always send correct origin
headers when connecting to an IPv6 websites. An attacker could potentially
use this to bypass intended access controls. (CVE-2012-0475)
Masato Kinugawa discovered that cross-site scripting (XSS) injection is
possible during the decoding of ISO-2022-KR and ISO-2022-CN character sets.
With cross-site scripting vulnerabilities, if a user were ...
