Sun(sm) Alert Notification
* Sun Alert ID: 102503
* Synopsis: Security Vulnerability in the X Inter Client Exchange
* Category: Security
* Product: Solaris 9 Operating System, Solaris 8 Operating System
* BugIDs: 6379034
* Avoidance: Patch
* State: Resolved
* Date Released: 13-Jul-2006
* Date Closed: 13-Jul-2006
* Date Modified:
A local or remote unprivileged user may be able to crash an
application which dynamically links to the X Inter Client Exchange
library (libICE) due to a security vulnerability in libICE. The
ability to crash an application is a type of Denial of Service (DoS).
A number of applications which comprise the GNOME desktop environment
dynamically link with libICE.
2. Contributing Factors
This issue can occur in the following releases:
* Solaris 8 without patch 119067-02
* Solaris 9 without patch 112785-53
* Solaris 8 without patch 119068-02
* Solaris 9 without patch 112786-42
Note: Solaris 10 is not affected by this issue.
To determine if an application is linked with the libICE library, the
ldd(1) utility can be utilized as in the following example:
$ ldd /usr/openwin/bin/xset | grep libICE
libICE.so.6 => /usr/openwin/lib/libICE.so.6
If the described issue occurs, the application which links to the
libICE library will exit and may generate an error message about a
Segmentation Fault and may also write a core(4) file.
There is no workaround. Please see the "Resolution" section below.
This issue is addressed in the following releases:
* Solaris 8 with patch 119067-02 or later
* Solaris 9 with patch 112785-53 or later
* Solaris 8 with patch 119068-02 or later
* Solaris 9 with patch 112786-42 or later
