LMH and KF have reported some vulnerabilities in Rumpus, which can be exploited by malicious, local users to gain escalated privileges and potentially by malicious users to compromise a vulnerable system.
1) The application invokes "ipfw" without an absolute path and has the setuid bit set. This can be exploited to gain "root" privileges by placing a specially crafted "ipfw" binary in the path.
2) Boundary errors within the FTP service can be exploited to cause heap-based buffer overflows and can potentially be exploited to execute arbitrary code via specially crafted packets.
Successful exploitation requires a valid user account.
The vulnerabilities are reported in version 5.1. Other versions may also be affected.
Solution: Update to version 5.1.1 or later.
