Immunix OS Security Advisory
Packages updated: openssh
Affected products: Immunix OS 7.0 and 6.2
Bugs fixed: immunix/1621, immunix/1706, immunix/1747
Date: Wed Oct 17 2001
Advisory ID: IMNX-2001-70-034-01
Author: Seth Arnold <[email protected]>
-----------------------------------------------------------------------
Description:
This release fixes several issues; two of moderate severity, and one
of slight severity. First, Peter W found that command restrictions
placed on keys did not apply to subsystems such as sftp, essentially
allowing users to bypass the command restrictions placed upon the key.
Second, the OpenSSH team found that IP source restrictions could be
bypassed when the authorized_keys file contained both RSA and DSA
keys. Last, zen-parse found that any file named 'cookies' could be
deleted remotely.
While Solar Designer's Openwall kernel patch prevents the third
problem from being exploited, the first two problems are likely
exploitable on Immunix OS computers, depending upon the local
configuration. OpenSSH release 2.9.9p2 fixes all three problems.
We recommend all users should upgrade OpenSSH. Markus notes in the
third reference some possible incompatibilities between version
2.9.9p2 and previous versions.
