Format string vulnerability in top program allows local attackers to gain root privileges via the "kill" or "renice" function.

procfs in FreeBSD and possibly other operating systems does not properly restrict access to per-process mem and ctl files, which allows local users to gain root privileges by forking a child process and executing a privileged process from the child, while the parent retains access to the child's address space.

rcvtty in BSD 3.0 and 4.0 does not properly drop privileges before executing a script, which allows local attackers to gain privileges by specifying an alternate Trojan horse script on the command line.

The catopen function in FreeBSD 5.0 and earlier, and possibly other OSes, allows local users to read arbitrary files via the LANG environmental variable.

The jail system call in FreeBSD 4.x before 4.10-RELEASE does not verify that an attempt to manipulate routing tables originated from a non-jailed process, which could allow local users to modify the routing table.

The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier.

ld.so in FreeBSD, NetBSD, and possibly other BSD distributions does not remove certain harmful environment variables, which allows local users to gain privileges by passing certain environment variables to loading processes. NOTE: this issue has been disputed by a third party, stating that it is the responsibility of the application to properly sanitize the environment
