Background ========= TestDisk is powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software: certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/testdisk < 7.0-r2 > = 7.0-r2 Description ========== A buffer overflow can be triggered within TestDisk when a malicious disk image is attempting to be recovered. Impact ===== A remote attacker could coerce the victim to run TestDisk against their malicious image. This may be leveraged by an attacker to crash TestDisk and gain control of program execution. Workaround ========= There is no known workaround at this time. Resolution ========= All TestDisk users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/testdisk-7.0" References ========= [ 1 ] TestDisk check_OS2MB Stack Buffer overflow Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201611-20 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.
