Package : dlt-daemon
Version : 2.18.0-1+deb10u1
CVE ID : CVE-2020-29394 CVE-2020-36244 CVE-2022-31291
Debian Bug : 976228 1014534

dlt-daemon, a Diagnostic Log and Trace logging daemon, had the following
vulnerabilities reported:

CVE-2020-29394

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

CVE-2020-36244

dlt-daemon was vulnerable to a heap-based buffer overflow that
could allow an attacker to remotely execute arbitrary code.

CVE-2022-31291

An issue in dlt_config_file_parser.c of dlt-daemon allows attackers
to cause a double free via crafted TCP packets.

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

We recommend that you upgrade your dlt-daemon packages.
