Squid PUT/POST denial of service
| squid-put-post-dos (19919) |  Low Risk |
Description:
Squid Web Proxy Cache is vulnerable to a denial of service attack, caused by a failed PUT/POST request. A remote attacker could exploit this vulnerability by sending a specially-crafted PUT/POST request to cause a segmentation fault or cause the program to enter into an inconsistent state.
