According to the versions of the squid packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Squid 3.x before 3.5.15 and 4.x before 4.0.7 does not     properly append data to String objects, which allows     remote servers to cause a denial of service (assertion     failure and daemon exit) via a long string, as     demonstrated by a crafted HTTP Vary     header.(CVE-2016-2569)

  - The Edge Side Includes (ESI) parser in Squid 3.x before     3.5.15 and 4.x before 4.0.7 does not check buffer     limits during XML parsing, which allows remote HTTP     servers to cause a denial of service (assertion failure     and daemon exit) via a crafted XML document, related to     esi/CustomParser.cc and     esi/CustomParser.h.(CVE-2016-2570)

  - http.cc in Squid 3.x before 3.5.15 and 4.x before 4.0.7     proceeds with the storage of certain data after a     response-parsing failure, which allows remote HTTP     servers to cause a denial of service (assertion failure     and daemon exit) via a malformed     response.(CVE-2016-2571)

  - http.cc in Squid 4.x before 4.0.7 relies on the HTTP     status code after a response-parsing failure, which     allows remote HTTP servers to cause a denial of service     (assertion failure and daemon exit) via a malformed     response.(CVE-2016-2572)

  - Squid 3.x before 3.5.16 and 4.x before 4.0.8 improperly     perform bounds checking, which allows remote attackers     to cause a denial of service via a crafted HTTP     response, related to Vary headers.(CVE-2016-3948)
