CVE-2023-2861 [LOW] QEMU regression
Title: QEMU regression
Summary: USN-6567-1 introduced a regression in QEMU.
USN-6567-1 fixed vulnerabilities QEMU. The fix for CVE-2023-2861 was too
restrictive and introduced a behaviour change leading to a regression in
certain environments. This update fixes the problem.
Original advisory details:
Gaoning Pan and Xingwei Li discovered that QEMU incorrectly handled the
USB xHCI controller device. A privileged guest attacker could possibly use
this issue to cause QEMU to crash, leading to a denial of service. This
issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2020-14394)

CVE-2020-24165 [HIGH] CWE-416 QEMU: use-after-free in TCG accelerator can lead to local privilege escalation
QEMU: use-after-free in TCG accelerator can lead to local privilege escalation
An issue was discovered in TCG Accelerator in QEMU 4.2.0, allows local attackers to execute arbitrary code, escalate privileges, and cause a denial of service (DoS). Note: This is disputed as a bug and not a valid security issue by multiple third parties.
A use-after-free vulnerability was found in the Tiny Code Generator (TCG) Accelerator in QEMU, where the TCG generated code can be in the same memory as the TB data structure. This flaw allows attackers to overwrite the UAF pointer with code produced from TCG and rewrite key pointer values, possibly leading to local privilege escalation and enabling code execution on the host outside of the TCG sandbox.
