>> Outgun Multiple Remote Buffer Overflow and Denial of Service Vulnerabilities
|
Multiple vulnerabilities have been identified in Outgun, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
The first issue is due to a buffer overflow error in the "servnet.cpp" script when handling overly long "type" and "name" arguments passed to the "data_file_request" command, which could be exploited by remote attackers to compromise a vulnerable system.
The second flaw is due to errors in the leetnet functions [leetnet/rudp.cpp] that do not properly handle overly large packets, which could be exploited by attackers to crash a vulnerable application.
The third vulnerability is due to memory corruption errors in the leetnet functions [leetnet/rudp.cpp] that do not properly handle an invalid message size field, which could be exploited by remote attackers to crash a vulnerable application.
The fourth issue is due to a buffer overflow error in the "changeRegistration()" [servernet.cpp] function, which could be exploited by attackers to modify the information of other players.
