TencentOS Server 3: virt and virt-devel (TSSA-2023:0110)

high Nessus Plugin ID 238965

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 multiple vulnerabilities as referenced in the TSSA-2023:0110 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:
CVE-2021-46790:
A vulnerability was found in NTFS-3G, specifically in the ntfsck utility. Incorrect validation of NTFS metadata can result in a heap-based buffer overflow when processing a crafted NTFS image file or partition.
CVE-2022-3165:
An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service.
CVE-2022-30784:
A vulnerability was found in NTFS-3G. Incorrect validation of NTFS metadata can result in a heap exhaustion when processing a crafted NTFS image file or partition.
CVE-2022-30786:
A vulnerability was found in NTFS-3G. Incorrect validation of NTFS metadata can result in a heap-based buffer overflow when processing a crafted NTFS image file or partition.
CVE-2022-30788:
A vulnerability was found in NTFS-3G. Incorrect validation of NTFS metadata can result in a heap-based buffer overflow when processing a crafted NTFS image file or partition.
CVE-2022-30789:
A vulnerability was found in NTFS-3G. Incorrect validation of NTFS metadata can result in a heap-based buffer overflow when processing a crafted NTFS image file or partition.
CVE-2023-1018:
An out-of-bound read vulnerability was found in the TPM 2.0's Module Library, which allows the reading of 2-byte data after the end of the TPM command. This flaw allows an attacker to leak confidential data stored within the libtpms context.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
