TencentOS Server 3: virt and virt-devel (TSSA-2023:0118)

medium Nessus Plugin ID 276387

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2023:0118 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:
CVE-2022-4144:
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest's physical address, potentially reading past the end of the bar space into adjacent pages. This could allow a malicious guest user to crash the QEMU process on the host, causing a denial of service. Spice was found to be affected by the same CVE.

Tenable has extracted the preceding description block directly from the Tencent 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.

Solution

Update the affected packages.
