Squid 3.x < 3.4.8 Multiple Vulnerabilities
Medium Nessus Plugin ID 79742
SynopsisThe remote proxy server may be affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of Squid running on the remote host is 3.x prior to 3.4.8. Therefore, it may be affected by the following vulnerabilities :
- A 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)
Note that Nessus has relied only on the version in the proxy server's banner. The patch released to address the issue does not update the version in the banner. If the patch has been applied properly, and the service has been restarted, consider this to be a false positive.
SolutionUpgrade to Squid version 3.4.8 or later, or apply the vendor-supplied patch.
