Official Description
Blue Coat ProxySG before 6.2.14.1, 6.3.x, 6.4.x, and 6.5 before 6.5.2 allows remote attackers to cause a denial of service (memory consumption and dropped connections) via a recursive href in an HTML page, which triggers a large number of HTTP RW pipeline pre-fetch requests.
Technical Analysis
CVE-2013-5959 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
