Background ========== The Gnumeric spreadsheet is a versatile application developed as part of the GNOME Office project. libpcre is a library providing functions for Perl-compatible regular expressions. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/gnumeric < 1.4.3-r2 >= 1.4.3-r2 Description =========== Gnumeric contains a private copy of libpcre which is subject to an integer overflow leading to a heap overflow (see GLSA 200508-17). Impact ====== An attacker could potentially exploit this vulnerability by tricking a user into opening a specially crafted spreadsheet, which could lead to the execution of arbitrary code with the privileges of the user running Gnumeric. 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-1.4.3-r2" References ========== [ 1 ] CAN-2005-2491 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2491 [ 2 ] GLSA 200508-17 http://www.gentoo.org/security/en/glsa/glsa-200508-17.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200509-02.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.
