('binary' encoding is not supported, stored as-is) Package: Portmon Auth: http://www.aboleo.net/ Version(s): 1.7 (prior ?) Vulnerability: File arbitrary read/write access vulnerability Portmon is a network service monitoring daemon (http://www.aboleo.net/software/portmon/). "In order to use ping support, Portmon must run as root or be installed setuid with root permissions due to the fact that it must open up a raw socket." The product suffer from a security problem that allows any local user to read/write protected files on the system. This is dude to a hole in the way the program handles loading of two configuration files: host file/log file.
