Rule Category

BROWSER-OTHER -- Snort has detected suspicious traffic known to exploit vulnerabilities present in an Internet browser other than Firefox, Internet Explorer, or Chrome, or which is present in multiple browsers. This rule should be enabled for systems that use any mainstream browser, to offer complete coverage. (ie, If a vulnerability affects both Chrome and Firefox, but is covered by a rule under the Chrome category, Firefox users might have Chrome coverage turned off and miss the vulnerability.)

Alert Message

Rule Explanation

Opera before 10.53 on Windows and Mac OS X does not properly handle a series of document modifications that occur asynchronously, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via JavaScript that writes sequences in an infinite loop, leading to attempted use of uninitialized memory. NOTE: this might overlap CVE-2006-6955.
