Squid 3.x < 3.4.8 Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 8634
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote proxy server is affected by multiple vulnerabilities.


Versions of Squid 3.4.x prior to 3.4.8 are potentially affected by by the following vulnerabilities :

- An off-by-one overflow flaw exists within the SNMP processing component. By using a specially crafted UDP SNMP request, a remote attacker could exploit this to cause a denial of service or possibly execute arbitrary code. (CVE-2014-6270)

- There exists an array indexing flaw in the node pinger that is triggered when parsing ICMP and ICMPv6 replies, which may allow a remote attacker to crash the pinger or obtain sensitive information. (CVE-2014-7141)

- The node pinger has a flaw in function 'Icmp4::Recv' in file 'icmp/Icmp4.cc' that is triggered when parsing ICMP or ICMPv6 responses. A remote attacker could exploit this to crash the pinger or obtain sensitive information. (CVE-2014-7142)


Either upgrade to Squid version 3.4.8 or later, or apply the vendor-supplied patch.
