FreeBSD orville-write Local Overflow
Local Access Required Input Manipulation
Loss of Integrity

A local overflow exists in orville-write, a FreeBSD port. The "huh" utility is setuid root and fails to validate input resulting in a buffer overflow. With a specially crafted request, an attacker can obtain escalated privileges resulting in a loss of integrity.

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround(s): (1) remove the orville-write port if you have installed it, (2) remove the setuid bit from the huh utility, (3) upgrade your entire ports collection and rebuild the orville-write port, (4) reinstall a new package dated after the correction date, (5) download a new port skeleton, and (6) use the portcheckout utility to automate aforementioned option (5). Execution of option (2): #chmod u-s /usr/local/bin/huh
