Debian DLA-3231-1 : dlt-daemon - LTS security update

critical Nessus Plugin ID 168488

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3231 advisory.

- 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). (CVE-2020-29394)

- The daemon in GENIVI diagnostic log and trace (DLT), is vulnerable to a heap-based buffer overflow that could allow an attacker to remotely execute arbitrary code on the DLT-Daemon (versions prior to 2.18.6).
(CVE-2020-36244)

- An issue in dlt_config_file_parser.c of dlt-daemon v2.18.8 allows attackers to cause a double free via crafted TCP packets. (CVE-2022-31291)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the dlt-daemon packages.

For Debian 10 buster, these problems have been fixed in version 2.18.0-1+deb10u1.
