SA Document Body
A security vulnerability in the LZW decoding function of the Solaris Tag
Image File Format Library libtiff(3):
1. Impact
A security vulnerability in the LZW decoding function of the Solaris
Tag Image File Format Library libtiff(3) may allow a local or remote
unprivileged user to crash applications that use this function via a
crafted TIFF image. The ability to crash an application is a type of
Denial of Service (DoS).
This issue is also described in the following document:
* CVE-2009-2285 at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-2285
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* GNOME 2.0 (for Solaris 8)
* Solaris 9
* Solaris 10
* OpenSolaris based upon builds snv_01 through snv_98
x86 Platform
* GNOME 2.0 (for Solaris 8)
* Solaris 9
* Solaris 10
* OpenSolaris based upon builds snv_01 through snv_98
Note 1: Sun includes libtiff(3) on the Solaris Companion CD for
Solaris 8
(http://wwws.sun.com/software/solaris/freeware/index.html) as an
unsupported package which installs to "/opt/sfw" and is vulnerable to
this issue. Sites using libtiff(3) from the Solaris Companion CD will
require an upgrade to a later version.
Note 2: This issue only affect systems which have the libtiff(3)
library installed. This library is part of the SUNWTiff package. To
determine if the SUNWTiff package is installed on Solaris 8, 9, and
10, the pkginfo(1) command can be used:
$ pkginfo -q SUNWTiff && echo "SUNWTiff is installed"
Note 3: 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
3. Symptoms
There are no predictable symptoms that would indicate this issue has
been exploited to cause a Denial of Service (DOS) condition.
4. Workaround
To work around the described issues, do not load TIFF images from
untrusted sources.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* OpenSolaris based upon builds snv_99 or later
x86 Platform
* OpenSolaris based upon builds snv_99 or later
A final resolution is pending completion for Solaris 8, 9, and 10.
