Background ========== OpenOffice.org is an office productivity suite, including word processing, spreadsheet, presentation, data charting, formula editing and file conversion facilities. libcurl, which is included in OpenOffice.org, is a free and easy-to-use client-side library for transferring files with URL syntaxes, supporting numerous protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/openoffice-bin < 2.0.2 >= 2.0.2 2 app-office/openoffice < 2.0.1-r1 >= 2.0.1-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== OpenOffice.org includes libcurl code. This libcurl code is vulnerable to a heap overflow when it tries to parse a URL that exceeds a 256-byte limit (GLSA 200512-09). Impact ====== An attacker could entice a user to call a specially crafted URL with OpenOffice.org, potentially resulting in the execution of arbitrary code with the rights of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All OpenOffice.org binary users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.0.2" All OpenOffice.org users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.0.1-r1" References ========== [ 1 ] CVE-2005-4077 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-4077 [ 2 ] Hardened-PHP Advisory 24/2005 http://www.hardened-php.net/advisory_242005.109.html [ 3 ] GLSA 200512-09 http://www.gentoo.org/security/en/glsa/glsa-200512-09.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200603-25.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.
