GNU : Security Vulnerabilities, CVEs, Published In October 2000

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.
