The remote host is affected by the vulnerability described in GLSA-200802-02 (Doomsday: Multiple vulnerabilities)
Luigi Auriemma discovered multiple buffer overflows in the D_NetPlayerEvent() function, the Msg_Write() function and the NetSv_ReadCommands() function. He also discovered errors when handling chat messages that are not NULL-terminated (CVE-2007-4642) or contain a short data length, triggering an integer underflow (CVE-2007-4643).
Furthermore a format string vulnerability was discovered in the Cl_GetPackets() function when processing PSV_CONSOLE_TEXT messages (CVE-2007-4644).
Impact :
A remote attacker could exploit these vulnerabilities to execute arbitrary code with the rights of the user running the Doomsday server or cause a Denial of Service by sending specially crafted messages to the server.
Workaround :
There is no known workaround at this time.
