Date of Resolved Release

A security vulnerability in the X Inter Client Exchange library (libICE):

1. Impact

A security vulnerability in the X Inter Client Exchange library (libICE) may allow a local or remote unprivileged user to crash an application that dynamically links to libICE.  The ability to crash an application is a type of Denial of Service (DoS).

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform
  • Solaris 8 without patch 119067-11
  • Solaris 9 without patch 112785-65
  • Solaris 10 without patch 119059-46
x86 Platform
  • Solaris 8 without patch 119068-11
  • Solaris 9 without patch 112786-54
  • Solaris 10 without patch 119060-45
  • OpenSolaris based upon builds snv_01 through snv_84
Note 1: OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived.

To determine the base build of  OpenSolaris, the following command can be used:
 
    $ uname -v
    snv_86
Note 2: Only OpenSolaris installations including the affected library "/usr/lib/libICE.so.6" or the corresponding 64-bit library, "/usr/lib/amd64/libICE.so.6" are impacted by this issue.

To determine if an application is linked with the libICE library, the ldd(1) utility can be utilized:
    $ ldd /usr/openwin/bin/xset | grep libICE
    libICE.so.6 =>   /usr/openwin/lib/libICE.so.6
Note 3:  Applications that don't list the libICE library as a dynamic dependency in the ldd(1) output may open the library during process execution using functions such as dlopen(3C) and therefore may still be impacted.

3. Symptoms

If the described issue occurs, the application linked to the libICE library will exit. A Segmentation Fault error message and core(4) file may be generated. A typical stack trace will be similar to the following:
    fed37065 _IceRead (8196cf0, 8, 81aca00) + ad
    fed374e6 IceProcessMessages (8196cf0, 0, 0) + 42
A number of applications that are comprised of the GNOME desktop environment dynamically link with libICE.  This may cause users to be logged out of the GNOME desktop environment with a dialog message stating that the Gnome session manager has crashed.  When this dialog box is closed, the session exits.

4. Workaround

There is no workaround for this issue. Please see the Resolution section below.

5. Resolution

This issue is addressed in the following releases:

SPARC Platform
  • Solaris 8 with patch 119067-11 or later
  • Solaris 9 with patch 112785-65 or later
  • Solaris 10 with patch 119059-46 or later
x86 Platform
  • Solaris 8 with patch 119068-11 or later
  • Solaris 9 with patch 112786-54 or later
  • Solaris 10 with patch 119060-45 or later
  • OpenSolaris based upon builds snv_85 or later
