In InfraStack/OSDependent/Linux/InfraStackModules/TraceModule/TraceModule.c, function Trace_OpenLogFile, the log file (typically /var/log/wimax/wimaxd.log) is chmod'ed to 0666. Log files should not be world-writable. I'm not sure if this log file should even be world-readable (see bug 911121). It's probably best to restrict permissions on the /var/log/wimax directory, too.
A security flaw was found in the way Trace module of WiMAX, an user space daemon for the Intel 2400m Wireless WiMAX link, used to set permissions when opening the log file (was created with world-readable / writable permissions). A local attacker could use this flaw to, in an unauthorized way, alter the content of WiMAX daemon log file (possibly leading to un-enforced actions to be performed by system administrator).
