"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2022:0189 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2021-41229:
    BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in
    sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates
    and will not be freed. This will cause a memory leak over time. The data can be a very large object, which
    can be caused by an attacker continuously sending sdp packets and this may cause the service of the target
    device to crash.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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