Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects. Security Fix: * 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. Red Hat would like to thank Amos Jeffries for reporting this issue.
