Squid 3.5.x < 3.5.15 Multiple Vulnerabilities
medium Nessus Network Monitor Plugin ID 9774
Synopsis
The remote proxy server is affected by multiple attack vectors.Description
Versions of Squid 3.5.x prior to 3.5.15 are affected by multiple vulnerabilities :- A flaw is triggered when performing improper bounds checks on specially crafted HTTP responses. This may allow a remote attacker to cause a denial of service.
- A flaw is triggered as bounds are not properly checked when processing HTTP responses. This may allow a remote attacker to cause a denial of service for all clients accessing the service.
- An overflow condition exists in the 'Icmp6::Recv()' function in 'icmp/Icmp6.cc' of the pinger binary. The issue is triggered as user-supplied input is not properly validated when handling specially crafted ICMPv6 packets. This may allow a remote attacker to cause a buffer overflow, crashing the pinger process or potentially leaking data into log files.
Solution
Either upgrade to Squid version 3.5.15 or later, or apply the vendor-supplied patch.See Also
