Background ========== The Gnumeric spreadsheet is a versatile application developed as part of the GNOME Office project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/gnumeric < 1.8.1 >= 1.8.1 Description =========== Multiple integer overflow and signedness errors have been reported in the excel_read_HLINK() function in file plugins/excel/ms-excel-read.c when processing XLS HLINK opcodes. Impact ====== A remote attacker could entice a user to open a specially crafted XLS file, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All Gnumeric users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/gnumeric-1.8.1" References ========== [ 1 ] CVE-2008-0668 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0668 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200802-05.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.
