Background ========== pdftohtml is a utility to convert PDF files to HTML or XML formats. It makes use of Xpdf code to decode PDF files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/pdftohtml <= 0.36 >= 0.36-r1 Description =========== Xpdf is vulnerable to multiple integer overflows, as described in GLSA 200410-20. Impact ====== An attacker could entice a user to convert a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running pdftohtml. Workaround ========== There is no known workaround at this time. Resolution ========== All pdftohtml users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/pdftohtml-0.36-r1" References ========== [ 1 ] GLSA 200410-20 http://www.gentoo.org/security/en/glsa/glsa-200410-20.xml [ 2 ] CAN-2004-0888 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0888 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-30.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.
