Turbolinux Advisory ID#: TLSA2002001
Credits: http://www.securityfocus.com/bid/3369 http://www.debian.org/security/2001/dsa-091 ___________________________________________________________________________
A security hole was discovered in the package mentioned above. Please update the package in your installation as soon as possible. ___________________________________________________________________________
1. Problem Summary
If the UseLogin feature is enabled in ssh local users could pass environment variables to the login process.
2. Impact
A user can gain root privileges.
3. Solution
This has been fixed by not copying the environment if UseLogin is enabled.
Update the following packages from our ftp server by running the following command:
rpm -Uvh ftp://ftp.turbolinux.com/pub/updates/6.0/security/<rpm>
Where <rpm> are the following:
openssl-0.9.6b-1.i386.rpm openssl-devel-0.9.6b-1.i386.rpm openssh-2.9p2-6.i386.rpm openssh-askpass-2.9p2-6.i386.rpm openssh-askpass-gnome-2.9p2-6.i386.rpm openssh-clients-2.9p2-6.i386.rpm openssh-sever-2.9p2-6.i386.rpm
The source RPM can be downloaded from:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/openssl-0.9.6b-1.src.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/openssh-2.9p2-6.src.rpm
**Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you install:
