TencentOS Server 4: frr (TSSA-2024:0607)

high Nessus Plugin ID 239339

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0607 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2023-3748:
A flaw was found in FRRouting when parsing certain babeld unicast hello messages that are intended to be ignored. This issue may allow an attacker to send specially crafted hello messages with the unicast flag set, the interval field set to 0, or any TLV that contains a sub-TLV with the Mandatory flag set to enter an infinite loop and cause a denial of service.

CVE-2023-31490:
An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_attr_psid_sub() function.

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.
