Background ========== Video Disk Recorder (VDR) is a Linux-based digital video recorder. The VDR program handles the On Screen Menu system that offers complete control over channel settings, timers and recordings. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/vdr < 1.2.6-r1 >= 1.2.6-r1 Description =========== Javier Fernandez-Sanguino Pena from the Debian Security Audit Team discovered that VDR accesses user-controlled files insecurely. Impact ====== A local attacker could create malicious links and invoke a VDR recording that would overwrite arbitrary files on the system. Workaround ========== There is no known workaround at this time. Resolution ========== All VDR users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-video/vdr-1.2.6-r1" References ========== [ 1 ] CAN-2005-0071 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0071 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-42.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.
