Background ========== HTMLDOC is a HTML indexer and HTML to PS and PDF converter. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/htmldoc < 1.8.27-r1 >= 1.8.27-r1 Description =========== ANTHRAX666 reported an insecure call to the sscanf() function in the set_page_size() function in htmldoc/util.cxx. Nico Golde of the Debian Security Team found two more insecure calls in the write_type1() function in htmldoc/ps-pdf.cxx and the htmlLoadFontWidths() function in htmldoc/htmllib.cxx. Impact ====== A remote attacker could entice a user to process a specially crafted HTML file using htmldoc, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. NOTE: Additional vectors via specially crafted AFM font metric files do not cross trust boundaries, as the files can only be modified by privileged users. Workaround ========== There is no known workaround at this time. Resolution ========== All HTMLDOC users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose =app-text/htmldoc-1.8.27-r1 References ========== [ 1 ] CVE-2009-3050 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3050 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200909-12.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.
