setpwnam.c in the util-linux package, as included in Red Hat Linux 7.3 and earlier, and other operating systems, does not properly lock a temporary file when modifying /etc/passwd, which may allow local users to gain privileges via a complex race condition that uses an open file descriptor in utility programs such as chfn and chsh.

time server daemon timed allows remote attackers to cause a denial of service via malformed packets.

Buffer overflow in (1) wrapping and (2) unwrapping functions of slrn news reader before 0.9.7.0 allows remote attackers to execute arbitrary commands via a long message header.

Format string vulnerability in Mutt before 1.2.5 allows a remote malicious IMAP server to execute arbitrary commands.

When using the LD_PRELOAD environmental variable in SUID or SGID applications, glibc does not verify that preloaded libraries in /etc/ld.so.cache are also SUID/SGID, which could allow a local user to overwrite arbitrary files by loading a library from /lib or /usr/lib.

kdesu program in KDE2 (KDE before 2.2.0-6) does not properly verify the owner of a UNIX socket that is used to send a password, which allows local users to steal passwords and gain privileges.

gpm 1.19.3 allows local users to overwrite arbitrary files via a symlink attack.

sdiff 2.7 in the diffutils package allows local users to overwrite files via a symlink attack.

rdist 6.1.5 allows local users to overwrite arbitrary files via a symlink attack.

getty_ps 2.0.7j allows local users to overwrite arbitrary files via a symlink attack.

useradd program in shadow-utils program may allow local users to overwrite arbitrary files via a symlink attack.

exmh 2.2 and earlier allows local users to overwrite arbitrary files via a symlink attack on the exmhErrorMsg temporary file.

privatepw program in wu-ftpd before 2.6.1-6 allows local users to overwrite arbitrary files via a symlink attack.

inn 2.2.3 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

arpwatch 2.1a4 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

squid 2.3 and earlier allows local users to overwrite arbitrary files via a symlink attack in some configurations.

Multiple shell programs on various Unix systems, including (1) tcsh, (2) csh, (3) sh, and (4) bash, follow symlinks when processing << redirects (aka here-documents or in-here documents), which allows local users to overwrite files of other users via a symlink attack.

Buffer overflow in ypserv in Mandrake Linux 7.1 and earlier, and possibly other Linux operating systems, allows an attacker to gain root privileges when ypserv is built without a vsyslog() function.

Format string vulnerability in ypserv in Mandrake Linux 7.1 and earlier, and possibly other Linux operating systems, allows an attacker to gain root privileges when ypserv is built without a vsyslog() function.

The default configuration of the Xsession file in Mandrake Linux 7.1 and 7.0 bypasses the Xauthority access control mechanism with an "xhost + localhost" command, which allows local users to sniff X Windows events and gain privileges.
