Background ========== OpenOffice.org is an office productivity suite, including word processing, spreadsheets, presentations, drawings, data charting, formula editing, and file conversion facilities. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/openoffice <= 1.1.1 >= 1.1.1-r1 2 app-office/openoffice <= 1.0.3-r1 >= 1.0.3-r2 3 app-office/openoffice <= 1.1.0-r3 >= 1.1.0-r4 4 app-office/openoffice-ximian <= 1.1.51 >= 1.1.51-r1 5 app-office/openoffice-ximian-bin <= 1.1.52 1.1.51-r1 6 app-office/openoffice-bin <= 1.1.1 1.1.51-r1 ------------------------------------------------------------------- # Package 1 [app-office/openoffice] only applies to X86 users. # Package 2 [app-office/openoffice] only applies to PPC users. # Package 3 [app-office/openoffice] only applies to SPARC users. NOTE: All packages listed without architecture tags apply to all architectures... ------------------------------------------------------------------- 6 affected packages ------------------------------------------------------------------- Description =========== OpenOffice.org includes code from the Neon library in functions related to publication on WebDAV servers. This library is vulnerable to several format string attacks. Impact ====== If you use the WebDAV publication and connect to a malicious WebDAV server, this server can exploit these vulnerabilities to execute arbitrary code with the rights of the user running OpenOffice.org. Workaround ========== As a workaround, you should not use the WebDAV publication facilities. Resolution ========== There is no binary version including the fix yet. All users of the openoffice-bin and ximian-openoffice-bin packages making use of the WebDAV publication functions should upgrade to the latest version of the corresponding source-based package. openoffice users on the x86 architecture should: # emerge sync # emerge -pv ">=app-office/openoffice-1.1.1-r1" # emerge ">=app-office/openoffice-1.1.1-r1" openoffice users on the sparc architecture should: # emerge sync # emerge -pv ">=app-office/openoffice-1.1.0-r3" # emerge ">=app-office/openoffice-1.1.0-r3" openoffice users on the ppc architecture should: # emerge sync # emerge -pv ">=app-office/openoffice-1.0.3-r1" # emerge ">=app-office/openoffice-1.0.3-r1" openoffice-ximian users should: # emerge sync # emerge -pv ">=app-office/openoffice-ximian-1.1.51-r1" # emerge ">=app-office/openoffice-ximian-1.1.51-r1" References ========== [ 1 ] CAN-2004-0179 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0179 [ 2 ] Neon vulnerabilities (GLSA 200405-01) http://www.gentoo.org/security/en/glsa/glsa-200405-01.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200405-04.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.
