Security Advisory Important: jakarta-commons-daemon-jsvc security update

Advisory: RHSA-2011:1292-1
Type: Security Advisory
Severity: Important
Issued on: 2011-09-14
Last updated on: 2011-09-14
Affected Products: JBoss Enterprise Web Server v1 EL4
CVEs ( CVE-2011-2729


An updated jakarta-commons-daemon-jsvc package that fixes one security
issue is now available for JBoss Enterprise Web Server 1.0 for Red Hat
Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

The jakarta-commons-daemon-jsvc package includes jsvc, a service wrapper
that allows Java applications to be run as daemons.

It was found that jsvc did not correctly drop capabilities after starting
an application. If an administrator used jsvc to run an application, and
also used the "-user" option to specify a user for it to run as, the
application correctly ran as that user but did not drop its increased
capabilities, allowing it access to all files and directories accessible to
the root user. (CVE-2011-2729)

Note: This flaw does not affect Red Hat Enterprise Linux 5 and 6, as the
jakarta-commons-daemon-jsvc packages for those products are not built with
capabilities support.

Users of JBoss Enterprise Web Server 1.0 for Red Hat Enterprise Linux 4
should upgrade to this updated package, which contains backported patches
to correct this issue. If jsvc is started, it must be restarted for this
update to take effect.


Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
