Infoseek's Ultraseek enterprise search server listens on port 8765 by default for HTTP commands. The code that handles GET commands has an unchecked buffer that will allow arbitrary code to be executed if it is overflowed.
A remote overflow exists in Infoseek Ultraseek. Infoseek Ultraseek fails to check the buffer boundary in GET command. By sending a specially crafted GET request via port 8765, a remote attacker can cause cause a buffer overflow and execute arbitrary code, resulting in a loss of integrity.
Upgrade to version 3.1.5 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
