TencentOS Server 4: frr (TSSA-2024:0605)

high Nessus Plugin ID 239910

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-2024:0605 advisory.

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

CVE-2024-34088:
In FRRouting (FRR) through 9.1, it is possible for the get_edge() function in ospf_te.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value, the OSPF daemon crashes, leading to denial of service.

CVE-2024-31950:
In FRRouting (FRR) through 9.1, there can be a buffer overflow and daemon crash in ospf_te_parse_ri for OSPF LSA packets during an attempt to read Segment Routing subTLVs (their size is not validated).

CVE-2024-31951:
In the Opaque LSA Extended Link parser in FRRouting (FRR) through 9.1, there can be a buffer overflow and daemon crash in ospf_te_parse_ext_link for OSPF LSA packets during an attempt to read Segment Routing Adjacency SID subTLVs (lengths are not validated).

CVE-2024-27913:
ospf_te_parse_te in ospfd/ospf_te.c in FRRouting (FRR) through 9.1 allows remote attackers to cause a denial of service (ospfd daemon crash) via a malformed OSPF LSA packet, because of an attempted access to a missing attribute field.

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.
