CVE-2016-2570

Name of the Vulnerable Software and Affected Versions Squid versions 3.x through 3.5.14 Squid versions 4.x through 4.0.6

Description The issue is related to the Edge Side Includes (ESI) parser in Squid, which does not properly check buffer limits during XML parsing. This allows remote HTTP servers to cause a denial of service, resulting in an assertion failure and daemon exit, by sending a crafted XML document. The problem is associated with the files esi/CustomParser.cc and esi/CustomParser.h.

Recommendations For Squid versions 3.x through 3.5.14, update to version 3.5.15 or later. For Squid versions 4.x through 4.0.6, update to version 4.0.7 or later.
