NVD Description

Note: Versions mentioned in the description apply only to the upstream dlt-daemon package and not the dlt-daemon package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

An issue was discovered in Connected Vehicle Systems Alliance (COVESA) dlt-daemon through 2.18.8. Due to a faulty DLT file parser, a crafted DLT file that crashes the process can be created. This is due to missing validation checks. There is a heap-based buffer over-read of one byte.
