Red Hat adminutil encoded input buffer overflow
| redhat-adminutil-encoded-input-bo (45203) |  High Risk |
Description:
Red Hat adminutil is vulnerable to a heap-based buffer overflow, caused by improper bounds checking when handling % character-encoded input. By sending a specially-crafted request to CGI scripts in Fedora Directory Server, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the daemon to crash.
