Secunia Advisory SA19698

Where:

From remote

Impact:

Security Bypass

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Eric Foley has discovered a weakness in Firefox, which can be exploited by malicious people to bypass certain security restrictions.

Internet web sites are normally not allowed to link to local resources. It is, however, possible by a malicious web site to open local content in the browser by tricking a user into right-clicking and choosing "View Image" on a broken image, which is referencing a local resource (e.g. via the file: URI handler).

NOTE: This does not pose any direct security impact by itself, but may be exploited in combination with other vulnerabilities.

The weakness has been confirmed in version 1.5.0.2. Other versions may also be affected.


Solution:
Update to version 1.5.0.4.
