Background ========== Opera is a multi-platform web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 8.51 >= 8.51 Description =========== Peter Zelezny discovered that the shell script used to launch Opera parses shell commands that are enclosed within backticks in the URL provided via the command line. Impact ====== A remote attacker could exploit this vulnerability by enticing a user to follow a specially crafted URL from a tool that uses Opera to open URLs, resulting in the execution of arbitrary commands on the targeted machine. Workaround ========== There is no known workaround at this time. Resolution ========== All Opera users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-8.51" References ========== [ 1 ] CVE-2005-3750 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3750 [ 2 ] Opera 8.51 Changelog http://www.opera.com/docs/changelogs/linux/851/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200512-10.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.
