Mozilla Firefox Image Preloading Content-Policy Check Security Bypass Vulnerability
危険度: 高
CVE識別番号: CVE-2010-0168
情報公開日: 2 15, 2011
概要
The nsDocument::MaybePreLoadImage function in
content/base/src/nsDocument.cpp in the image-preloading implementation in
Mozilla Firefox 3.6 before 3.6.2 does not apply scheme restrictions and policy
restrictions to the image's URL, which might allow remote attackers to cause a
denial of service (application crash or hang) or hijack the functionality of the
browser's add-ons via a crafted SRC attribute of an IMG element, as demonstrated
by remote command execution through an ssh: URL in a configuration that supports
gnome-vfs with a nonstandard network.gnomevfs.supported-protocols
setting.
