Opera Releases Urgent Security Upgrade

An update to the Opera browser was made available today, addressing a group of rather serious security vulnerabilities. Three separate issues fixed in version 9.63 - manipulating text area contents to cause a buffer overflow, triggering a crash by utilizing specific HTML constructs, and creating long host names in file: URLs - all could result in arbitrary code execution on a victim's machine if exploited properly. A flaw that allows for script injection when previewing a news feed, marked highly severe due to the fact that a hacker could view contents of any news feeds the victim is subscribed to, was also patched in this version. Another dangerous issue addressed involves Opera's built-in XSLT templates allowing for cross-site scripting.

Users are encouraged to upgrade to Opera 9.63 right away since all previous versions are vulnerable to the aforementioned issues as well as a couple of others.
