Synopsis
The remote proxy server is prone to a denial of service attack.Description
According to its banner, the version of the Squid proxy caching server installed on the remote host is older than 3.0.STABLE19 / 3.1.0.14 / 2.6.STABLE23. A bug in the 'strListGetItem()' function in 'src/HttpHeaderTools.c' can result in an infinite loop when processing a specially crafted auth header with certain comma delimiters.A remote attacker may be able to leverage this issue to cause a denial of service.
Solution
Upgrade to Squid version 3.0.STABLE19 / 3.1.0.14 / 2.6.STABLE23 or later.See Also
