7.2 HIGH — AV:L/AC:L/Au:N/C:C/I:C/A:C

Description

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.

Affected configurations

• gnu glibc 2.1.1
