Synopsis: Moderate: condor security, bug fix and enhancement update

Advisory ID: RHSA-2008:0911-01

Product: Red Hat Enterprise MRG for RHEL-5

Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0911.html

Issue date: 2008-10-07

CVE-2008-3830

=====================================================================

 

1. Summary:

 

Updated condor packages that address multiple security issues, fix several

bugs, and introduce feature enhancements are now available for Red Hat

Enterprise MRG 1.0 for Red Hat Enterprise Linux 5.

 

This update has been rated as having moderate security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

MRG Grid for RHEL 5 Server - 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.
