| Detailed Description |
The relevant host is running a version of Squid caching proxy which is older than 3.5.9. Squid is a freely available Web Proxy server for Linux and Unix distributions. Squid Web Proxy Cache versions prior to 3.5.9 is affected by the following vulnerabilities:
- A denial of service vulnerability exists in file bio.cc when handling hello messages. A remote attacker can exploit this to cause an infinite loop. (OSVDB 127754)
- An integer overflow condition exists in file bio.cc due to improper validation of user-supplied input. A remote attacker can exploit this to crash the proxy, resulting in a denial of service. (OSVDB 127762)
* Note: This check solely relied on the version number of the remote Squid Web Proxy Cache server to assess this vulnerability, so this might be a false positive.
