Summary: Updated libtiff packages that fix several security issues are now available for Red Hat Enterprise Linux 3, 4, and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Description: The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files. Several integer overflow flaws, leading to heap-based buffer overflows, were found in various libtiff color space conversion tools. An attacker could create a specially-crafted TIFF file, which once opened by an unsuspecting user, would cause the conversion tool to crash or, potentially, execute arbitrary code with the privileges of the user running the tool. (CVE-2009-2347) A buffer underwrite flaw was found in libtiff's Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could create a specially-crafted LZW-encoded TIFF file, which once opened by an unsuspecting user, would cause an application linked with libtiff to access an out-of-bounds memory location, leading to a denial of service (application crash). (CVE-2009-2285) The CVE-2009-2347 flaws were discovered by Tielei Wang from ICST-ERCIS, Peking University. All libtiff users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, all applications linked with the libtiff library (such as Konqueror) must be restarted for the update to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 507465 - CVE-2009-2285 libtiff: LZWDecodeCompat underflow 510041 - CVE-2009-2347 libtiff: integer overflows in various inter-color spaces conversion tools (crash, ACE) 6.
