Summary: A jsvc update for JBoss Enterprise Web Server 1.0.2 on Red Hat Enterprise Linux 4 that fixes one security issue is now available from the Red Hat Customer Portal. 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. 2. Description: jsvc is 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 only affected users running JBoss Enterprise Web Server 1.0.2 from jboss-ews-1.0.2-RHEL4-[arch].zip as provided from the Red Hat Customer Portal, as versions for other products are not built with capabilities support. All users running JBoss Enterprise Web Server 1.0.2 as provided from the Red Hat Customer Portal on Red Hat Enterprise Linux 4 are advised to apply this update. 3. Solution: The References section of this erratum contains a download link (you must log in to download the update). Before applying the update, backup your existing JBoss Enterprise Web Server installation (including all applications and configuration files). After applying the update, if jsvc is started, it must be restarted for this update to take effect. 4.
