CVE 検索

GNU ed before 0.2-18.1 allows local users to overwrite the files of other users via a symlink attack.

GnuPG (gpg) 1.0.3 does not properly check all signatures of a file containing multiple documents, which allows an attacker to modify contents of all documents but the first without detection.

glibc2 does not properly clear the LD_DEBUG_OUTPUT and LD_DEBUG environmental variables when a program is spawned from a setuid program, which could allow local users to overwrite files via a symlink attack.

Format string vulnerability in cfd daemon in GNU CFEngine before 1.6.0a11 allows attackers to execute arbitrary commands via format characters in the CAUTH command.

GNU Groff uses the current working directory to find a device description file, which allows a local user to gain additional privileges by including a malicious postpro directive in the description file, which is executed when another user runs groff.

Mailman 1.1 allows list administrators to execute arbitrary commands via shell metacharacters in the %(listname) macro expansion.

The unsetenv function in glibc 2.1.1 does not properly unset an environmental variable if the variable is provided twice to a program, which could allow local users to execute arbitrary commands in setuid programs by specifying their own duplicate environmental variables such as LD_PRELOAD or LD_LIBRARY_PATH.

The -ftrapv compiler option in gcc and g++ 3.3.3 and earlier does not handle all types of integer overflows, which may leave applications vulnerable to vulnerabilities related to overflows.

GNU userv 1.0.0 and earlier does not properly perform file descriptor swapping, which can corrupt the USERV_GROUPS and USERV_GIDS environmental variables and allow local users to bypass some access restrictions.

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

The resolver in glibc 2.1.3 uses predictable IDs, which allows a local attacker to spoof DNS query results.

read-passwd and other Lisp functions in Emacs 20 do not properly clear the history of recently typed keys, which allows an attacker to read unencrypted passwords.

The make-temp-name Lisp function in Emacs 20 creates temporary files with predictable names, which allows attackers to conduct a symlink attack.

Emacs 20 does not properly set permissions for a slave PTY device when starting a new subprocess, which allows local users to read or modify communications between Emacs and the subprocess.

GNU make follows symlinks when it reads a Makefile from stdin, which allows other local users to execute commands.

The Guile plugin for the Gnumeric spreadsheet package allows attackers to execute arbitrary code.
