TencentOS Server 3: frr (TSSA-2024:0019)

high Nessus Plugin ID 238708

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-2024:0019 advisory.

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

CVE-2023-38406:
bgpd/bgp_flowspec.c in FRRouting (FRR) before 8.4.3 mishandles an nlri length of zero, aka a flowspec overflow.

CVE-2023-38407:
bgpd/bgp_label.c in FRRouting (FRR) before 8.5 attempts to read beyond the end of the stream during labeled unicast parsing.

CVE-2023-47234:
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when processing a crafted BGP UPDATE message with a MP_UNREACH_NLRI attribute and additional NLRI data (that lacks mandatory path attributes).

CVE-2023-47235:
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when a malformed BGP UPDATE message with an EOR is processed, because the presence of EOR does not lead to a treat-as-withdraw outcome.

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.
