Synopsis ========
A buffer overflow in TestDisk might allow remote attackers to execute arbitrary code.
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 ==========
