high Nessus Plugin ID 238898

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-2024:0184 advisory.

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

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.

CVE-2023-41358:
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute length is zero.

CVE-2023-41909:
An issue was discovered in FRRouting FRR through 9.0. bgp_nlri_parse_flowspec in bgpd/bgp_flowspec.c processes malformed requests with no attributes, leading to a NULL pointer dereference.

CVE-2023-46752:
A data mishandling vulnerability was found in FRRouting. A malformed MP_REACH_NLRI data can lead to a crash, resulting in a denial of service.

CVE-2023-46753:
A flaw was found in FRRouting. A crash can occur for a crafted BGP UPDATE message without mandatory attributes (for example, one with only an unknown transit attribute).

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.
