Background ========== sandbox is a Gentoo Linux utility used by the Portage package management system. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/sandbox < 1.2.11 >= 1.2.11 Description =========== The Gentoo Linux Security Audit Team discovered that the sandbox utility was vulnerable to multiple TOCTOU (Time of Check, Time of Use) file creation race conditions. Impact ====== Local users may be able to create or overwrite arbitrary files with the permissions of the root user. Workaround ========== There is no known workaround at this time. Resolution ========== All sandbox users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/sandbox-1.2.11" Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200507-22.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.
