Background ========== file is a utility used to identify the type of a file. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/file < 4.12 >= 4.12 Description =========== A possible stack overflow has been found in the ELF header parsing code of file. Impact ====== An attacker may be able to create a specially crafted ELF file which, when processed with file, may allow the execution of arbitrary code. 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-4.12" References ========== [ 1 ] SecurityTracker Alert ID 1012433 http://securitytracker.com/id?1012433 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200412-07.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.
