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 = 0.0.4 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 https://www.cve.org/CVERecord?id=CVE-CAN-2004-1288 [ 2 ] Wiktor Kopec advisory Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200501-20 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.
