TencentOS Server 3: edk2 (TSSA-2024:0190)

high Nessus Plugin ID 240041

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-2024:0190 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

CVE-2022-36763:
A heap buffer overflow flaw was found via the Tcg2MeasureGptTable() function in EDK2, arising from inadequate validation of the GPT Primary Header, presenting a minor risk to confidentiality and integrity.
The primary consequence is likely a crash or denial of service. This issue may allow a local attacker to craft a GPT table, causing an integer overflow and consequent buffer overflow.

CVE-2022-36764:
A heap-based buffer overflow flaw was found via the Tcg2MeasurePeImage() function in EDK2. Successful exploitation requires a local attacker to trigger an integer overflow in the calculation of the EventSize variable at DxeTpm2MeasureBootLib.c, leading to the heap-buffer overflow, presenting a moderate risk to confidentiality and integrity. However, the primary consequence is likely a crash or denial of service.

CVE-2022-36765:
A flaw was found in the CreateHob() function in EDK2. An attacker, leveraging a local network, can initiate an integer overflow leading to a buffer overflow. This issue arises during size alignment within the CreateHob() function, requiring activation in the PEI phase. Successful exploitation of this flaw poses a moderate threat to confidentiality and integrity, however, the primary consequence is likely a crash or denial of service.

CVE-2023-45229:
A vulnerability has been identified in the NetworkPkg IP stack of EDK2, the open-source reference implementation of the UEFI specification. This flaw enables an unauthenticated attacker within the same network vicinity to transmit a specifically crafted DHCPv6 message. Exploiting this vulnerability may result in unauthorized access to memory beyond its boundaries, potentially leading to the exposure of sensitive information.

CVE-2023-45231:
A security loophole involving an out-of-bounds read was identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker within the vicinity of the network to transmit a specifically crafted Neighbor Discovery Redirect message.
Consequently, this may lead to the unauthorized reading of memory beyond the message boundaries, potentially resulting in the exposure of sensitive information.

CVE-2023-45232:
A security loophole involving an infinite loop was identified in EDK2, the open-source reference implementation of the UEFI specification. This weakness enables an unauthorized attacker to exploit system availability by sending a specifically crafted Destination Options IPv6 header.

CVE-2023-45233:
The Network Package in EDK2 is vulnerable to an infinite loop exploit when parsing a PadN option within the Destination Options header of IPv6. This flaw allows an unauthorized attacker to gain access and potentially result in a loss of system availability.

CVE-2023-45235:
A security flaw involving buffer overflow was identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker within the vicinity network to transmit a specifically crafted DHCPv6 proxy Advertise message, resulting in the disclosure of information and potential compromise of system availability.

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.
