Multiple Security Vulnerabilities in the libexpat Library May Lead to a Denial of Service (DoS) Condition

1. Impact

Multiple security vulnerabilities have been identified in libexpat, a library for parsing XML files. These vulnerabilities may allow a local or remote unprivileged user to create a crafted XML file that may cause an application linked with libexpat to crash, resulting in a Denial of Service (DoS) condition.

Additional information regarding these issues is available at:


2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform
  • Solaris 10 without patch 137147-05
  • OpenSolaris based upon builds snv_01 through snv_129
x86 Platform
  • Solaris 10 without patch 137148-05
  • OpenSolaris based upon builds snv_01 through snv_129
Note: Solaris 8 and 9 do not bundle libexpat, therefore are not impacted by these issues.

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_111
3. Symptoms

If the described issues have been exploited, the application which makes use of the libexpat library will crash, potentially leaving a core file depending on the system configuration.

4. Workaround

There is no workaround for these issues. Please see the Resolution section below.

5. Resolution

These issues are addressed in the following releases:

SPARC Platform
  • Solaris 10 with patch 137147-05 or later
  • OpenSolaris based upon builds snv_130 or later
x86 Platform
  • Solaris 10 with patch 137148-05 or later
  • OpenSolaris based upon builds snv_130 or later
