As far as we can tell, there is only one vulnerability -- it is 
associated with 
http://bugs.squid-cache.org/show_bug.cgi?id=4066#c3

Use CVE-2014-9749.

We aren't currently providing any statement about the affected 
versions for this vulnerability. It is possible that 
http://bugs.squid-cache.org/show_bug.cgi?id=4066#c7 implies that 
3.5.x wasn't ever vulnerable, but that the 3.5.x code was replaced
 anyway because it had used too slow of an approach to preventing 
the vulnerability.



3.5 had the same issue before patching. But additional
fix was required for a secondary bug found once the main issue was
patched.

The released versions I am currently aware of having this issue are:
 3.4.4 -> 3.4.11 inclusive
 3.5.0.1 -> 3.5.1 inclusive

versions older than 3.4.4 have not been investigated yet to my knowledge
.
