The address parser code in Postfix 1.1.12 and earlier allows remote attackers to cause a denial of service (lock) via (1) a malformed envelope address to a local host that would generate a bounce and contains the ".!" string in the MAIL FROM or Errors-To headers, which causes nqmgr to lock up, or (2) via a valid MAIL FROM with a RCPT TO containing a ".!" string, which causes an instance of the SMTP listener to lock up.

skk (Simple Kana to Kanji conversion program) 12.1 and earlier, and the ddskk package which is based on skk, creates temporary files insecurely, which allows local users to overwrite arbitrary files.

The /proc filesystem in Linux allows local users to obtain sensitive information by opening various entries in /proc/self before executing a setuid program, which causes the program to fail to change the ownership and permissions of those entries.

The execve system call in Linux 2.4.x records the file descriptor of the executable process in the file table of the calling process, which allows local users to gain read access to restricted file descriptors.

Postfix 1.1.11 and earlier allows remote attackers to use Postfix to conduct "bounce scans" or DDos attacks of other hosts via an email address to the local host containing the target IP address and service name followed by a "!" string, which causes Postfix to attempt to use SMTP to communicate with the target on the associated port.

Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.

The kernel strncpy function in Linux 2.4 and 2.5 does not %NUL pad the buffer on architectures other than x86, as opposed to the expected behavior of strncpy as implemented in libc, which could lead to information leaks.

The RPC code in Linux kernel 2.4 sets the reuse flag when sockets are created, which could allow local users to bind to UDP ports that are used by privileged services such as nfsd.

A race condition in the way env_start and env_end pointers are initialized in the execve system call and used in fs/proc/base.c on Linux 2.4 allows local users to cause a denial of service (crash).

/proc/tty/driver/serial in Linux 2.4.x reveals the exact number of characters used in serial links, which could allow local users to obtain potentially sensitive information such as the length of passwords.

KDE Konqueror for KDE 3.1.2 and earlier does not remove authentication credentials from URLs of the "user:password@host" form in the HTTP-Referer header, which could allow remote web sites to steal the credentials for pages that link to the sites.

The imagemagick libmagick library 5.5 and earlier creates temporary files insecurely, which allows local users to create or overwrite arbitrary files.

Cross-site scripting (XSS) vulnerability in the transparent SID support capability for PHP before 4.3.2 (session.use_trans_sid) allows remote attackers to insert arbitrary script via the PHPSESSID parameter.

The (1) semi MIME library 1.14.5 and earlier, and (2) wemi 1.14.0 and possibly other versions, allows local users to overwrite arbitrary files via a symlink attack on temporary files.

Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.

Ethereal 0.9.12 and earlier does not handle certain strings properly, with unknown consequences, in the (1) BGP, (2) WTP, (3) DNS, (4) 802.11, (5) ISAKMP, (6) WSP, (7) CLNP, (8) ISIS, and (9) RMI dissectors.

The tvb_get_nstringz0 function in Ethereal 0.9.12 and earlier does not properly handle a zero-length buffer size, with unknown consequences.

The SPNEGO dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service (crash) via an invalid ASN.1 value.

The OSI dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via invalid IPv4 or IPv6 prefix lengths, possibly triggering a buffer overflow.

Unknown vulnerability in the DCERPC (DCE/RPC) dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service (memory consumption) via a certain NDR string.
