Background ========== file is a utility that guesses a file format by scanning binary data for patterns. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/file < 4.21 >= 4.21 ------------------------------------------------------------------- # Package 1 only applies to x86, PPC and HPPA users. Description =========== Colin Percival from FreeBSD reported that the previous fix for the file_printf() buffer overflow introduced a new integer overflow. Impact ====== A remote attacker could entice a user to run the file program on an overly large file (more than 1Gb) that would trigger an integer overflow on 32-bit systems, possibly leading to the execution of arbitrary code with the rights of the user running file. Workaround ========== There is no known workaround at this time. Resolution ========== Since file is a system package, all Gentoo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/file-4.21" References ========== [ 1 ] CVE-2007-2799 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2799 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200705-25.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.
