Background ========== PDFlib is a library providing functions to handle PDF files. It includes a modified TIFF library used to process TIFF images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/pdflib < 5.0.4_p1 >= 5.0.4_p1 Description =========== The TIFF library is subject to several known vulnerabilities (see GLSA 200410-11). Most of these overflows also apply to PDFlib. Impact ====== A remote attacker could entice a user or web application to process a carefully crafted PDF file or TIFF image using a PDFlib-powered program. This can potentially lead to the execution of arbitrary code with the rights of the program processing the file. Workaround ========== There is no known workaround at this time. Resolution ========== All PDFlib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/pdflib-5.0.4_p1" References ========== [ 1 ] PDFlib ChangeLog http://www.pdflib.com/products/pdflib/info/PDFlib-5.0.4p1-changes.txt [ 2 ] CAN-2004-0803 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0803 [ 3 ] CAN-2004-0804 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0804 [ 4 ] CAN-2004-0886 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0886 [ 5 ] GLSA 200410-11 http://www.gentoo.org/security/en/glsa/glsa-200410-11.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200412-02.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.
