Background ========== wv is a library for conversion of MS Word DOC and RTF files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/wv < 1.2.3-r1 >= 1.2.3-r1 Description =========== The wv library fails to do proper arithmetic checks in multiple places, possibly leading to integer overflows. Impact ====== An attacker could craft a malicious file that, when handled with the wv library, could lead to the execution of arbitrary code with the permissions of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All wv library users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/wv-1.2.3-r1" References ========== [ 1 ] CVE-2006-4513 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4513 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200612-01.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.
