Impact Multiple security vulnerabilities have been found in libtiff(3), a library for reading and writing Tag Image File Format (TIFF) files. These vulnerabilities may allow a remote unprivileged user to execute arbitrary code with the privileges of a local user if that local user has loaded a TIFF image file (.tiff) supplied by an untrusted user. The remote user may be able to crash the TIFF image viewing program as well. The TIFF image files may be picked up in e-mail or from an untrusted web site. These issues are described in the following documents: * CERT Vulnerability VU#948752 (http://www.kb.cert.org/vuls/id/948752) which is referenced in CAN-2004-0803 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0803) * CERT Vulnerability VU#555304 (http://www.kb.cert.org/vuls/id/555304) which is referenced in CAN-2004-0804 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0804) * CERT Vulnerability VU#687568 (http://www.kb.cert.org/vuls/id/687568) which is referenced in CAN-2004-0886 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0886) * CERT Vulnerability VU#125598 (http://www.kb.cert.org/vuls/id/125598) which is referenced in CAN-2004-1308 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1308) 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Solaris 7 (OpenWindows) without patch 118953-02 [1] * Solaris 8 (CDE) without patch 109931-10 [2] * Solaris 9 (CDE) without patch 114219-11 [3] * Solaris 9 (with package SUNWTiff or SUNWTiffx) * Solaris 10 (with package SUNWTiff installed) x86 Platform * Solaris 7 (OpenWindows) without patch 118954-02 [4] * Solaris 8 (CDE) without patch 109932-10 [5] * Solaris 9 (CDE) without patch 114220-11 [6] * Solaris 9 (with package SUNWTiff or SUNWTiffx) * Solaris 10 (with package SUNWTiff installed) Note 1: In Solaris 8 the libtiff(3) library may be installed in the following directories: /usr/openwin/lib (OpenWindows) /usr/dt/lib/sdtimage (CDE) In Solaris 9 the libtiff(3) library may be installed in the following directories: /usr/sfw/lib(SUNWTiff) /usr/sfw/lib/sparcv9 (SUNWTiffx) /usr/openwin/lib(OpenWindows) /usr/dt/lib/sdtimage (CDE) In Solaris 10 the libtiff(3) library may be installed in the following directories: /usr/lib /usr/lib/sparcv9 Note 2: 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 from the Solaris Companion CD will have to upgrade to a later version. 3. Symptoms There are no reliable symptoms that would show the described issues have been exploited. Solution Summary 4. Relief/Workaround To work around the described issues, do not load TIFF images from untrusted sources. 5. Resolution These issues are addressed in the following releases: SPARC Platform * Solaris 7 (OpenWindows) with patch 118953-02 [7] or later * Solaris 8 (CDE) with patch 109931-10 [8] or later * Solaris 9 (CDE) with patch 114219-11 [9] or later x86 Platform * Solaris 7 (OpenWindows) with patch 118954-02 [10] or later * Solaris 8 (CDE) with patch 109932-10 [11] or later * Solaris 9 (CDE) with patch 114220-11 [12] or later Note: This issue is not yet resolved in Solaris 9 (with package SUNWTiff or SUNWTiffx) A final resolution is pending completion.
