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.
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.
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.
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.
