CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE   : ghostscript
SUMMARY   : Temporary files and dynamic libraries
DATE      : 2000-12-08 16:31:00
ID        : CLA-2000:355
RELEVANT
RELEASES  : 6.0

DESCRIPTION (This is a specific update for Conectiva Linux 6.0, previous versions have already been updated.) "ghostscript" as shipped with Conectiva Linux has two security problems that could be used to get higher privileges on a system:
1) insecure temporary file handling could allow symlink attacks;
2) a compile time option that was incorrectly being used made ghostscript pick up dynamic libraries in the current directory instead of the system directories. These problems are now fixed.

SOLUTION
All users should upgrade to the new packages.
