__________________________________________________________________
Determining if your version is vulnerable:
Squid-3.0:
All Squid-3.0 versions up to and including 3.0.STABLE25 have
some risk of being vulnerable to variations of the problem.
The particular 0-day tests currently known do not trigger it.
Squid-3.1:
All versions up to and including 3.1.7 are at some risk of being
vulnerable to the problem and its variations.
squid.conf containing with "ignore_expect_100 on" are vulnerable
to the known active 0-day.
Binaries built with --disable-http-violations are not vulnerable
to the known active 0-day.
Squid-3.2:
The 3.2.0.1 beta version is vulnerable under the same conditions
as for Squid-3.1.
__________________________________________________________________
Workarounds:
These workarounds apply only to the known active 0-day triggers.
1) Checking that ignore_expect_100 squid.conf option is set to
"off" (the default), or removed completely from squid.conf.
or,
2) Building Squid with --disable-http-violations.

387 Captain Parks, however, agreed with Mr. Everdail, who trusted him absolutely—if Sandy did not—that it would be wise not to give any person who had been on the yacht during its crossing any chance to get away. Felipa stood leaning listlessly against the post of the ramada, watching them. After a time she went into the adobe and came out with a pair of field-glasses, following the course of the command as it wound along among the foot-hills. The day dragged dully along. She was uneasy about her husband, her nerves were shaken with the coffee and quinine, and she was filled,[Pg 76] moreover, with a vague restlessness. She would have sent for her horse and gone out even in the clouds of dust and the wind like a hot oven, but Landor had forbidden her to leave the post. Death in the tip of a poisoned arrow, at the point of a yucca lance, or from a more merciful bullet of lead, might lurk behind any mesquite bush or gray rock.
