Library may lead to arbitrary code execution or Denial of Service (DoS)

Date of Resolved Release: 06-May-2008
SA Document Body
Security Vulnerabilities in the Tcl GUI Toolkit Library may lead to
arbitrary code execution or Denial of Service (DoS)
1. Impact
Multiple security vulnerabilities in the Tcl GUI Toolkit (libtk(3LIB))
may allow a remote unprivileged user who provides a specially crafted
GIF image to cause a denial of service (DoS) to applications using the
libtk library to process images or execute arbitrary code with the
privileges of the user running such applications.

CVE-2007-5378 at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5378
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 9 without patch 137910-01
* Solaris 10 without patch 137871-01
x86 Platform
* Solaris 9 without patch 137911-01
* Solaris 10 without patch 137872-01
Note: Solaris 8 does not include support for libtk(3LIB) and is not
impacted by this issue.
3. Symptoms
If these issues are exploited to cause a Denial of Service (DoS), the
application which makes use of the libtk(3LIB) library to process the
crafted GIF image may crash. There are no predictable symptoms that
would indicate that the issues have been exploited to execute
arbitrary code or shell commands.
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 9 with patch 137910-01 or later
* Solaris 10 with patch 137871-01 or later
x86 Platform
* Solaris 9 with patch 137911-01 or later
