Race condition in the UFS and EXT2FS file systems in FreeBSD 4.2 and earlier, and possibly other operating systems, makes deleted data available to user processes before it is zeroed out, which allows a local user to access otherwise restricted information.
IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.
ipfw and ip6fw in FreeBSD 4.2 and earlier allows remote attackers to bypass access restrictions by setting the ECE flag in a TCP packet, which makes the packet appear to be part of an established connection.
Buffer overflow in catopen() function in FreeBSD 5.0 and earlier, and possibly other OSes, allows local users to gain root privileges via a long environmental variable.
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 setlocale function in FreeBSD 5.0 and earlier, and possibly other OSes, allows local users to read arbitrary files via the LANG environmental variable.
Buffer overflow in the Linux binary compatibility module in FreeBSD 3.x through 5.x allows local users to gain root privileges via long filenames in the linux shadow file system.
libedit searches for the .editrc file in the current directory instead of the user's home directory, which may allow local users to execute arbitrary commands by installing a modified .editrc in another directory.
