Background ========== libTIFF provides support for reading and manipulating TIFF images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/tiff < 3.8.2-r1 >= 3.8.2-r1 Description =========== A buffer overflow has been found in the t2p_write_pdf_string function in tiff2pdf, which can been triggered with a TIFF file containing a DocumentName tag with UTF-8 characters. An additional buffer overflow has been found in the handling of the parameters in tiffsplit. Impact ====== A remote attacker could entice a user to load a specially crafted TIFF file, resulting in the possible execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All libTIFF users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r1" References ========== [ 1 ] CVE-2006-2193 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2193 [ 2 ] CVE-2006-2656 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2656 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200607-03.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
