** Description changed: [Impact] + The squid initscript has a guard against configuration mistakes that prevents the service from being disrupted if the current config has an invalid setting. - * An explanation of the effects of the bug on users and + This guard relies on the "squid -k parse" command which analyzes the + configuration and, in the case of a fatal problem, outputs the string + "FATAL: <reason>".

When I look in the source package I find two init scripts: squid3.rc and squid.rc. squid3.rc has the patch while squid.rc does not. The one being included in the package and deployed is the one that does not have the fix. I'm including a patch to fix this issue. Please push this out ASAP.
