Insight
The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Multiple uses of uninitialized values were discovered in libtiff's Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked with libtiff to crash or, possibly, execute arbitrary code. (CVE-2008-2327)
Red Hat would like to thank Drew Yao of the Apple Product Security team for reporting this issue.
A buffer overflow flaw was discovered in the tiff2pdf conversion program distributed with libtiff. An attacker could create a TIFF file containing UTF-8 characters that would, when converted to PDF format, cause tiff2pdf to crash, or, possibly, execute arbitrary code. (CVE-2006-2193)
Additionally, these updated packages fix the following bug:
* the libtiff packages included manual pages for the sgi2tiff and tiffsv commands, which are not included in these packages. These extraneous manual pages were removed.
All libtiff users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
