Squid 3.x < 3.4.8 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 8634

Synopsis

The remote proxy server is affected by multiple vulnerabilities.

Description

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)

Solution

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