Conquest metaGetServerList() buffer overflow
| conquest-metagetserverlist-bo (32849) |  High Risk |
Description:
Conquest is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the metaGetServerList() function in meta.c. By sending a specially-crafted request from a malicious server, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash, if the attacker could convince the victim to connect to a malicious server.

- CVE-2007-1371: Multiple buffer overflows in Conquest 8.2a and earlier (1) allow local users to gain privileges by querying a metaserver that sends a long server entry processed by metaGetServerList and allow remote metaservers to execute arbitrary code via a long server entry processed by metaGetServerList; (2) allow attackers to have an unknown impact by exceeding the configured number of metaservers; and allow remote attackers to corrupt memory via a SP_CLIENTSTAT packet with certain values of (3) unum or (4) snum, different vulnerabilities than CVE-2003-0933.
