New Firefox release fixes three security issues
A new version of the Firefox web browser has been released. Firefox 188.8.131.52 fixes three security vulnerabilities:
- Referer-spoofing via window.location race condition – It was possible to generate a fake HTTP Referer header by exploiting a timing condition when setting the window.location property. This could be used to conduct a Cross-site Request Forgery (CSRF) attack against websites that rely only on the Referer header as protection against such attacks.
- Memory corruption vulnerabilities (rv:184.108.40.206) – The Firefox 220.127.116.11 update contains fixes for three bugs that improve the stability of the product. These crashes showed some evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
- jar: URI scheme XSS hazard – The jar: URI scheme was introduced as a mechanism to support digitally signed web pages, enabling web sites to load pages packaged in zip archives containing signatures in java-archive format. This means that sites that allow users to upload binary content in zip format are effectively allowing users to install web pages on their site, and these can be used to perform Cross-Site Scripting (XSS) attacks.
Mozilla provides Firefox 2 for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Firefox 2 here.
