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.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2827 advisory.

    Several vulnerabilities were discovered in BlueZ, the Linux Bluetooth protocol stack. An attacker could     cause a denial-of-service (DoS) or leak information. CVE-2019-8921 SDP infoleak; the vulnerability lies in     the handling of a SVC_ATTR_REQ by the SDP implementation of BlueZ. By crafting a malicious CSTATE, it is     possible to trick the server into returning more bytes than the buffer actually holds, resulting in     leaking arbitrary heap data. CVE-2019-8922 SDP Heap Overflow; this vulnerability lies in the SDP protocol     handling of attribute requests as well. By requesting a huge number of attributes at the same time, an     attacker can overflow the static buffer provided to hold the response. CVE-2021-41229 sdp_cstate_alloc_buf     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.
    For Debian 9 stretch, these problems have been fixed in version 5.43-2+deb9u5. We recommend that you     upgrade your bluez packages.
