The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds read in the -sample operation when processing a specific offset supplied through the sample:offset define. A remote attacker can supply a crafted offset value to cause a denial of service.

User interaction is required to process the crafted input.
