I'm also using Google Chrome. Another concern for me - its setup downloads: http://cache.pack.google.com/chrome/install/149.30/chrome_installer.exe which is not signed by authenticode. Can anyone post hashes of this file downloaded over a trusted network? Or, is this info available at some trusted sources? Thanks in advance, On 9/24/08, Aditya K Sood <0kn0ck () secniche org> wrote:
*Google Chrome Carriage Return Null Object Memory Exhaustion Remote Dos.* *Version Affected:* Chrome/0.2.149.30 Chrome/0.2.149.29 *Severity:* High *Description:* The Google chrome browser is vulnerable to memory exhaustion based denial of service which can be triggered remotely.The vulnerability triggers when Carriage Return(\r\n\r\n) is passed as an argument to window.open() function. It makes the Google Chrome to generate number of windows at the same time thereby leading to memory exhaustion. The behavior can be easily checked by looking at the task manager as with no time the memory usage rises high. The problem lies in the handling of object and its value returned by the javascript function. Once it is triggered the pop ups are started generating. The Google Chrome browser generate object windows continuously there by affecting memory of the resultant system. Probably it can be crashed within no time. User interaction is required in this. *Proof of Concept* http://www.secniche.org/gds *Links:* http://secniche.org/gcrds.html http://evilfingers.com/advisory/Google_Chrome_Carriage_Return_Null_Object_Memory_Exhaustion_Remote_Dos.php *Detection:* SecNiche confirmed this vulnerability affects Google Chrome on Microsoft Windows XP SP2 platform.The versions tested are: Chrome/0.2.149.30 Chrome/0.2.149.291 *Disclosure Timeline:* Disclosed: 22 September 2008 Release Date.
