 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.
