Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5416 advisory.

 - client.c in gdhcp in ConnMan through 1.41 could be used by network-adjacent attackers (operating a crafted DHCP server) to cause a stack-based buffer overflow and denial of service, terminating the connman process. (CVE-2023-28488)

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

Solution

Upgrade the connman packages.

For the stable distribution (bullseye), this problem has been fixed in version 1.36-2.2+deb11u2.
