--------------------------------------------------------------------- Red Hat, Inc. Security Advisory
Synopsis: New ncurses packages fixing buffer overrun available Advisory ID: RHSA-2000:115-02 Issue date: 2000-11-23 Updated on: 2000-11-26 Product: Red Hat Linux Keywords: ncurses buffer overrun exploit setuid Cross references: N/A ---------------------------------------------------------------------
1. Topic:
If you are any setuid applications that use ncurses and its cursor movement
functionality, local users may gain access to the program's privileges.
2000-11-27: Added packages for Red Hat Linux 7 for Alpha
2. Relevant releases/architectures:
Red Hat Linux 6.2 - i386, alpha, sparc Red Hat Linux 6.2EE - i386, alpha, sparc Red Hat Linux 7.0 - i386, alpha
3. Problem description:
There used to be an overflowable buffer in the part of the ncurses library
handling cursor movement.
Attackers can force a privileged application to use their own termcap file
containing a special terminal entry which will trigger the ncurses
vulnerability, allowing them to execute arbitrary code with the privileges
of the exploited binary.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
20809 - ncurses allows local privilege escalation
