[****** START APACHE BULLETIN HERE ******] Fixed in Apache httpd 2.2.7-dev low: mod_proxy_balancer DoS CVE-2007-6422 A flaw was found in the mod_proxy_balancer module. On sites where mod_proxy_balancer is enabled, an authorized user could send a carefully crafted request that would cause the Apache child process handling that request to crash. This could lead to a denial of service if using a threaded Multi-Processing Module. Affects: 2.2.6, 2.2.5, 2.2.4, 2.2.3, 2.2.2, 2.2.0 low: mod_proxy_balancer XSS CVE-2007-6421 A flaw was found in the mod_proxy_balancer module. On sites where mod_proxy_balancer is enabled, a cross-site scripting attack against an authorized user is possible. Affects: 2.2.6, 2.2.5, 2.2.4, 2.2.3, 2.2.2, 2.2.0 moderate: mod_status XSS CVE-2007-6388 A flaw was found in the mod_status module. On sites where mod_status is enabled and the status pages were publicly accessible, a cross-site scripting attack is possible. Note that the server-status page is not enabled by default and it is best practice to not make this publicly available. Affects: 2.2.6, 2.2.5, 2.2.4, 2.2.3, 2.2.2, 2.2.0 moderate: mod_imagemap XSS CVE-2007-5000 A flaw was found in the mod_imagemap module. On sites where mod_imagemap is enabled and an imagemap file is publicly available, a cross-site scripting attack is possible. Affects: 2.2.6, 2.2.5, 2.2.4, 2.2.3, 2.2.2, 2.2.0 [****** END APACHE BULLETIN HERE ******] _______________________________________________________________________________ CIAC wishes to acknowledge the contributions of Apache for the information contained in this bulletin. _______________________________________________________________________________ CIAC, the Computer Incident Advisory Capability, is the computer security incident response team for the U.S. Department of Energy (DOE) and the emergency backup response team for the National Institutes of Health (NIH).
