Squid 3.x < 3.4.8 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)
