Doc Text:
It was found that the fix for CVE-2016-4051 released via RHSA-2016:1138 did not properly prevent the stack overflow in the munge_other_line() function. A remote attacker could send specially crafted data to the Squid proxy, which would exploit the cachemgr CGI utility, possibly triggering execution of arbitrary code.
