Background ========== The file utility attempts to identify a file's format by scanning binary data for patterns. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/file < 5.21 >= 5.21 Description =========== An issue with the ELF parser used by the file utility can cause a resource consumption when reading a specially-crafted ELF binary. Impact ====== A context-dependent attacker may be able to cause Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All file users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/file-5.21" References ========== [ 1 ] CVE-2014-8117 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-8117 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201412-48.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.
