Title:	Debian: Security Advisory (DLA-2827-1)
Summary:	The remote host is missing an update for the Debian 'bluez' package(s) announced via the DLA-2827-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'bluez' package(s) announced via the DLA-2827-1 advisory. Vulnerability Insight: 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. For the detailed security status of bluez please refer to its security tracker page at: [link moved to references] Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references] Affected Software/OS: 'bluez' package(s) on Debian 9.
