Category Security Release Phase Resolved Solaris 9 Operating System Solaris 10 Operating System Solaris 8 Operating System Bug Id 6412202 Date of Workaround Release 11-OCT-2007 Date of Resolved Release 03-Sep-2008 Multiple Security Vulnerabilities in the Solaris Tag Image File Format Library libtiff(3) 1. Impact Multiple security vulnerabilities in the Solaris Tag Image File Format library (libtiff(3)) may allow a local or remote unprivileged user to crash applications that dynamically link to the "libtiff" library and execute arbitrary code with the privileges of a local user. The ability to crash an application that links to the "libtiff" library is a type of Denial of Service (DoS). Solaris ships several applications as part of the GNOME Desktop Environment that dynamically link with the "libtiff" library. These issues are described in the following documents: CVE-2006-2024 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2024 CVE-2006-2025 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2025 CVE-2006-2026 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2026 Sun acknowledges with thanks, Tavis Ormandy from the Google Security Team for bringing these issues to our attention. 2. Contributing Factors These issues can occur in the following releases: SPARC Platform
3. Symptoms There are no predictable symptoms that would indicate these issues have been exploited to cause a Denial of Service or execute arbitrary code with the privileges of a local user. 4. Workaround The stack overflow security issues referenced in this document may be worked around by using the "noexec_user_stack" option. This can be achieved by editing the "/etc/system" file and adding the following lines: set noexec_user_stack = 1Note: A reboot will be necessary in order for this change to take effect. See system(4) for more information on modifying the "/etc/system" file. To workaround the remaining issues described in this document, do not load images from untrusted sources. 5. Resolution This issue is addressed in the following releases: SPARC Platform
