The fix for this CVE strongly relies on exception handling present in more recent versions of squid3, that I failed to identify in the previous update. I have reverted the patch to take the safest position, taking into account that Squeeze users should migrate to a supported version of Debian. This post-EOL update is intended to keep a functional squid3 package in the archive.");
