-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0949 -- [Win][UNIX/Linux][RedHat] Moderate: condor security, bug fix and enhancement update 8 October 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Condor Publisher: Red Hat Operating System: Red Hat Linux 5 Red Hat Linux 4 UNIX variants (UNIX, Linux, OSX) Windows Impact: Execute Arbitrary Code/Commands Inappropriate Access Denial of Service Access: Existing Account CVE Names: CVE-2008-3830 CVE-2008-3829 CVE-2008-3828 CVE-2008-3826 Original Bulletin: https://rhn.redhat.com/errata/RHSA-2008-0924.html https://rhn.redhat.com/errata/RHSA-2008-0911.html Comment: This advisory references vulnerabilities in products which run on platforms other than RedHat. It is recommended that administrators running Condor check for an updated version of the software for their operating system. Revision History: October 8 2008: Added bulletin for Red Hat Linux 5 October 8 2008: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: condor security, bug fix and enhancement update Advisory ID: RHSA-2008:0924-01 Product: Red Hat Enterprise MRG for RHEL-4 Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0924.html Issue date: 2008-10-07 CVE Names: CVE-2008-3826 CVE-2008-3828 CVE-2008-3829 CVE-2008-3830 ===================================================================== 1. Summary: Updated condor packages that fix multiple security issues, several bugs and introduce feature enhancements are now available for Red Hat Enterprise MRG 1.0 for Red Hat Enterprise Linux 4. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat MRG Grid for RHEL-4 AS - i386, x86_64 Red Hat MRG Grid for RHEL-4 ES - i386, x86_64 3. Description: Condor is a specialized workload management system for compute-intensive jobs. It provides a job queuing mechanism, scheduling policy, priority scheme, and resource monitoring and management. A flaw was found in the way Condor processed user submitted jobs. It was possible for a user to submit a job in a way that could cause that job to run as a different user with access to the pool. (CVE-2008-3826) A stack based buffer overflow flaw was found in Condor's condor_schedd daemon. A user who had permissions to submit a job could do so in a manner that could cause condor_schedd to crash or, potentially, execute arbitrary code with the permissions of condor_schedd. (CVE-2008-3828) A denial-of-service flaw was found in Condor's condor_schedd daemon. A user who had permissions to submit a job could do so in a manner that would cause condor_schedd to crash. (CVE-2008-3829) A flaw was found in the way Condor processes allowed and denied netmasks for access control. If a configuration file contained an overlapping netmask in the allow or deny rules, it could cause that rule to be ignored, allowing unintended access. (CVE-2008-3830) This update also fixes the following bugs: * the "amazon_gahp -m" command sets the AMAZON_GAHP_WORKER_MAX_NUM configuration option, fixing the maximum number of processes contacting EC2 at any given time. Previously, Condor did not honor this option, leaving the maximum number of created threads unbounded. This has been corrected: values set with the "-m" argument are now properly understood. * the gridmanager constructed KeyPairs for all outstanding EC2 jobs before any jobs are started. When there were many (>10,000) EC2 jobs in the queue, significant delays occurred. With this update, KeyPairs are no longer constructed up-front. * an error in condor_negotiator caused intialization code to re-run whenever condor_reconfig was run. The flag which noted if the initialization code should run was always set to "true". This error has been corrected: the initialization code now executes only at startup. As well, this update adds the following enhancements: * this release introduces Concurrency Limits. These allow Condor to account for resources not directly under its control, such as software licenses. * this update includes the latest stable upstream release of Condor: version 7.0.5. Information on the features and fixes included with this release are in the Condor Release Notes, available via the link in the References section below. * base support for low-latency scheduling and transparent translation of EC2 jobs has also been added in this update. Note: implementation of these two features depends on separate packages which are yet to be released. All Red Hat Enterprise MRG 1.0 users are advised to upgrade to these updated packages which address these vulnerabilities, fix these bugs and add these enhancements. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network.
