Package : connman
Version : 1.36-2.1~deb10u4
CVE ID : CVE-2023-28488
Debian Bug : 1034393

It was discovered that there was a potential denial of service
vulnerabilty in connman, a command-line network manager designed for
use on embedded devices.

Network-adjacent attackers operating a crafted DHCP server could have
caused a stack-based buffer overflow, resulting in a denial of
service through terminating the connman process.

For Debian 10 buster, this problem has been fixed in version
1.36-2.1~deb10u4.

We recommend that you upgrade your connman packages.
