CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE : openssh
SUMMARY : Local vulnerability in OpenSSH
DATE : 2001-12-13 18:12:00
ID : CLA-2001:446

RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0

DESCRIPTION
OpenSSH is a freely available, open source implementation of the
Secure Shell protocol. It provides secure encrypted communication
between two untrusted hosts over an insecure network.
The OpenSSH developers released[1] a new version of OpenSSH which
fixes a local vulnerability[2] related to the "UseLogin" option. If
this option is enabled, local users may be able to pass arbitrary
environment variables to the "login" process. By setting LD_PRELOAD
and using a malicious shared library, an attacker might execute
arbitrary code as root.
Please note that Conectiva Linux does not have the "UseLogin" option
enabled by default. Therefore, it's not vulnerable to attacks unless
the system administrator has turned it on.
SOLUTION
It is recommended that all OpenSSH users upgrade their packages. This
upgrade will restart the service if it's already running.
