A vulnerability has been found in the Apache HTTP Server.
CVE-2015-3183
Apache HTTP Server did not properly parse chunk headers, which allowed remote attackers to conduct HTTP request smuggling via a crafted request. This flaw relates to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c.
For the squeeze distribution, these issues have been fixed in version 2.2.16-6+squeeze15 of apache2.
We recommend you to upgrade your apache2 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
