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.

Buffer overflow in KON kon2 0.3.9b and earlier allows local users to execute arbitrary code via a long -Coding command line argument.

Unknown vulnerability in the TTY layer of the Linux kernel 2.4 allows attackers to cause a denial of service ("kernel oops").

The mxcsr code in Linux kernel 2.4 allows attackers to modify CPU state registers via a malformed address.

Unknown vulnerability in GNU Ghostscript before 7.07 allows attackers to execute arbitrary commands, even when -dSAFER is enabled, via a PostScript file that causes the commands to be executed from a malicious print job.

The TCP/IP fragment reassembly handling in the Linux kernel 2.4 allows remote attackers to cause a denial of service (CPU consumption) via certain packets that cause a large number of hash table collisions.

lv reads a .lv file from the current working directory, which allows local users to execute arbitrary commands as other lv users by placing malicious .lv files into other directories.

tcpdump does not properly drop privileges to the pcap user when starting up.

A patch for shadow-utils 20000902 causes the useradd command to create a mail spool files with read/write privileges of the new user's group (mode 660), which allows other users in the same group to read or modify the new user's incoming email.

The default configuration of the pam_xauth module forwards MIT-Magic-Cookies to new X sessions, which could allow local users to gain root privileges by stealing the cookies from a temporary .xauth file, which is created with the original user's credentials after root uses su.

Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.

Memory leak in ypdb_open in yp_db.c for ypserv before 2.5 in the NIS package 3.9 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of requests for a map that does not exist.

dvips converter for Postscript files in the tetex package calls the system() function insecurely, which allows remote attackers to execute arbitrary commands via certain print jobs, possibly involving fonts.

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.

Exim 3.22 and earlier, in some configurations, does not properly verify the local part of an address when redirecting the address to a pipe, which could allow remote attackers to execute arbitrary commands via shell metacharacters.

Format string vulnerability in exim (3.22-10 in Red Hat, 3.12 in Debian and 3.16 in Conectiva) in batched SMTP mode allows a remote attacker to execute arbitrary code via format strings in SMTP mail headers.

The wrapper program in mailman 2.0beta3 and 2.0beta4 does not properly cleanse untrusted format strings, which allows local users to gain privileges.

userhelper in the usermode package on Red Hat Linux executes non-setuid programs as root, which does not activate the security measures in glibc and allows the programs to be exploited via format string vulnerabilities in glibc via the LANG or LC_ALL environment variables (CVE-2000-0844).

Red Hat Linux screen program does not use Unix98 ptys, allowing local users to write to other terminals.

Buffer overflow in Linux linuxconf package allows remote attackers to gain root privileges via a long parameter.
