Site packetfence.org

PacketFence is a network access control (NAC) system. It is actively maintained and has been deployed in numerous large-scale institutions. It can be used to effectively secure networks, from small to very large heterogeneous networks. PacketFence provides NAC-oriented features such as registration of new network devices, detection of abnormal network activities including from remote snort sensors, isolation of problematic devices, remediation through a captive portal, and registration-based and scheduled vulnerability scans.

Changes: Various fixes and updates.

issetugid() + rsh + libmalloc OS X Local Root
Posted Oct 3, 2015
Authored by Philip Pettersson

The default root-suid binary /usr/bin/rsh on Mac OS X uses execv() in an insecure manner. /usr/bin/rsh will invoke /usr/bin/rlogin if launched with only a host argument, without dropping privileges or clearing the environment. This exploit will pass "MallocLogFile" to /usr/bin/rsh, which is then passed on to rlogin and interpreted by libmalloc to create a root-owned file with partially controlled contents at /etc/crontab which gives a rootshell via sudo. Tested on 10.9.5 / 10.10.5 but it most likely works on much older versions too.
