dlt-daemon: CVE-2020-29394

Severity: Medium
Published: Nov 30, 2020, 7:15:00 PM UTC
Source: [NVD] · [CVE record]
EPSS: 1.94% · Oct 25, 2026

A buffer overflow in the dlt_filter_load function in dlt_common.c from dlt-daemon through 2.18.5 (GENIVI Diagnostic Log and Trace) allows arbitrary code execution because fscanf is misused (no limit on the number of characters to be read in the format argument).
