ALAS-2016-735


Amazon Linux AMI Security Advisory: ALAS-2016-735
Advisory Release Date: 2016-08-17 13:30 Pacific
Severity: Medium

Issue Overview:

A buffer overflow flaw was found in the way the Squid cachemgr.cgi utility processed remotely relayed Squid input. When the CGI interface utility is used, a remote attacker could possibly use this flaw to execute arbitrary code. (CVE-2016-4051 )

It was found that the fix for CVE-2016-4051 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 )
