Linux-Mandrake Security Update Advisory
________________________________________________________________________
Package name: usermode
Date: October 11th, 2000
Advisory ID: MDKSA-2000:059
Affected versions: None
________________________________________________________________________
Problem Description:
The usermode package contains the program userhelper which is used to
control access to programs which are to be executed as root. Because
programs invoked by userhelper are not actually running setuid-root,
security measures built into recent versions of glibc are not active.
If one of these programs supports internationalized text messages, a
malicious user can use the LANG or LC_ALL environment variables (which
are inherited by userhelper and any programs it runs) to create a
format-string exploit in these programs.
________________________________________________________________________
Linux-Mandrake ships an older version of usermode which is not
vulnerable to this problem. Linux-Mandrake 7.2 beta contains the fixed
usermode 1.36 as provided by Red Hat.
