Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

Safe.pm 2.0.7 and earlier, when used in Perl 5.8.0 and earlier, may allow attackers to break out of safe compartments in (1) Safe::reval or (2) Safe::rdo using a redefined @_ variable, which is not reset between successive calls.

Buffer overflow in Common Desktop Environment (CDE) ToolTalk RPC database server (rpc.ttdbserverd) allows remote attackers to execute arbitrary code via an argument to the _TT_CREATE_FILE procedure.

CDE ToolTalk database server (ttdbserver) allows local users to overwrite arbitrary files via a symlink attack on the transaction log file used by the _TT_TRANSACTION RPC procedure.

CDE ToolTalk database server (ttdbserver) allows remote attackers to overwrite arbitrary memory locations with a zero, and possibly gain privileges, via a file descriptor argument in an AUTH_UNIX procedure call, which is used as a table index by the _TT_ISCLOSE procedure.

Insecure file permissions for Netscape FastTrack Server 2.x, Enterprise Server 2.0, and Proxy Server 2.5 in SCO UnixWare 7.0.x and 2.1.3 allow an attacker to gain root privileges.

UnixWare pkgtrans allows local users to read arbitrary files via a symlink attack.

Denial of service in BIND named via naptr.
