Background ========== o3read is a standalone converter for OpenOffice.org files. It allows a user to dump the contents tree (o3read) and convert to plain text (o3totxt) or to HTML (o3tohtml) Writer and Calc files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/o3read <= 0.0.3 >= 0.0.4 Description =========== Wiktor Kopec discovered that the parse_html function in o3read.c copies any number of bytes into a 1024-byte t[] array. Impact ====== Using a specially crafted file, possibly delivered by e-mail or over the Web, an attacker may execute arbitrary code with the permissions of the user running o3read. Workaround ========== There is no known workaround at this time. Resolution ========== All o3read users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/o3read-0.0.4" References ========== [ 1 ] CAN-2004-1288 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1288 [ 2 ] Wiktor Kopec advisory http://tigger.uic.edu/~jlongs2/holes/o3read.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-20.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.
