CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : openssh
SUMMARY   : Remote vulnerabilities
DATE      : 2003-09-17 18:48:00
ID        : CLA-2003:741
RELEVANT
RELEASES  : 7.0, 8, 9

DESCRIPTION
 OpenSSH[1] is a very popular and versatile tool that uses encrypted
 connections between hosts and is commonly used for remote
 administration.
 
 This update fixes new vulnerabilities found in the code that handles
 buffers in OpenSSH. These vulnerabilities are similiar to the ones
 fixed in the CLSA-2003:739 announcement[2] (CAN-2003-0693) and can be
 exploited by a remote attacker to cause a denial of service condition
 and potentially execute arbitrary code (although there is still no
 concrete evidence of that).
 
 The Common Vulnerabilities and Exposures project (cve.mitre.org) has
 assigned the name CAN-2003-0695 to this additional issue[3].
 
 The OpenSSH team released the version 3.7.1 which fixes this
 vulnerability[4]. This update contains the versions originally
 distributed with Conectiva Linux added of backported patches.
 
 Additionally, patches made by Solar Designer to fix memory bugs in
 other parts of the code are being added. Althought it is unlikely
 that these bugs are exploitable, they are being treatead as security
 fixes by now and have the name CAN-2003-0682 assigned[5] by The
 Common Vulnerabilities and Exposures project (cve.mitre.org).


SOLUTION
 It is recommended that all OpenSSH users upgrade their packages.
 
 The ssh service will be automatically restarted during the upgrade if
 it is already running. Current ssh sessions will remain open during
 the restart.
