3. Description:
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.
Security Fix(es):
* 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. (CVE-2016-5408)
Red Hat would like to thank Amos Jeffries (Squid) for reporting this issue.
