Sun Java System Web Server Authorization: Digest header buffer overflow
| jsws-digest-header-bo (55792) |  High Risk |
Description:
Sun Java System Web Server is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the webservd and admin server. By sending an overly long request in an Authorization: Digest header, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the server to crash.
