Comment 1 Tomas Hoger 2008-03-31 15:50:29 UTC

Issue was previously tracked using bug bug #410181.

Comment 3 Tomas Hoger 2008-03-31 16:16:14 UTC

This issue was introduced in the original fix for SQUID-2007_2.  An attacker can
possibly cause squid child process to exit due to a failed assert.  New child
process is spawned by the parent squid process to replace exited child.  Child
process exit can easily interrupt current connections of other users.

Issue affects squid packages currently shipped in Red Hat Enterprise Linux 2.1,
3, 4, and 5.
