Dominique Dumont discovered that YAML-LibYAML did not correctly handle
certain reflection operations. If a user or system were tricked into
opening a specially crafted file, an attacker could possibly use this issue
to delete files. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04
LTS. (CVE-2017-20285)
It was discovered that YAML-LibYAML did not correctly handle parsing
certain documents. If a user or automated system were tricked into opening
a specially crafted file, an attacker could possibly use this issue to
execute arbitrary code. This issue only affected Ubuntu 16.04 LTS and
Ubuntu 18.04 LTS. (CVE-2019-25777)
It was discovered that YAML-LibYAML contained a regular expression
susceptible to catastrophic backtracking. If a user or automated system
were tricked into opening a specially crafted file, an attacker could

USN-8908-1 fixed vulnerabilities in BlueZ. Unfortunately, that update introduced a
regression in the A2DP profile: cached remote stream endpoints were no
longer loaded at startup, which could cause Bluetooth audio devices to
fail to reconnect automatically or to fall back to low-quality audio
profiles. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Michael Bommarito discovered that BlueZ incorrectly handled codec
capability storage in the A2DP profile. An attacker could possibly
use this issue to cause a stack buffer overflow, resulting in a denial
of service or arbitrary code execution. This issue only affected Ubuntu
20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS and Ubuntu 26.04 LTS.
(CVE-2026-19774)
It was discovered that BlueZ incorrectly handled packet length validation.
An attacker could possibly use this issue to read out of bounds memory,
causing a crash or exposing sensitive information. (CVE-2026-75032)
It was discovered that BlueZ incorrectly handled crafted XML input. An
attacker could possibly use this issue to crash BlueZ, resulting in a
denial of service. (CVE-2026-80185)
It was discovered that BlueZ incorrectly parsed remote names from Extended
Inquiry Response data. An attacker could possibly use this issue to cause a
stack buffer overflow, resulting in a denial of service or arbitrary code
execution. (CVE-2026-80186)
Alexandro Calo discovered that BlueZ incorrectly parsed certain responses
in the AVRCP profile. An attacker could possibly use this issue to access
out of bounds memory, causing a crash or exposing sensitive information.
