Moderate: condor security, bug fix and enhancement update
Security Advisory: Moderate
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.
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)
