DescriptionNVD

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).

AnalysisAI

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. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. 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). Affected products include: Genivi Diagnostic Log And Trace, Debian Debian Linux. Version information: through 2.18.5.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
