Description
Squid is a web proxy cache. Starting in version 3.5.27 and prior to version 6.8, Squid may be vulnerable to a Denial of Service attack against HTTP Chunked decoder due to an uncontrolled recursion bug.

In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. There is no workaround for this issue.
