Summary

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.

Common Weakness Enumeration (CWE)

CWE-125 - Out-of-bounds Read

Common Attack Pattern Enumeration and Classification (CAPEC)

Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
