Summary
A flaw was found in device-mapper-persistent-data. A local attacker can cause a Denial of Service (DoS) by inducing a user or system tool to process crafted device metadata containing an excessively large block index. An arithmetic error in the synchronous block reading logic causes the application to panic and unexpectedly terminate.
