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.

An update of the frr package has been released.

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6322 advisory.

    Several vulnerabilities were discovered in FRRouting (frr), a suite of     internet routing protocol daemons. A remote attacker could trigger these     issues by sending specially crafted protocol packets to a vulnerable     daemon, resulting in denial of service (infinite loops, NULL pointer     dereferences and crashes) or potentially the execution of arbitrary code     through out-of-bounds reads and writes and buffer overflows. The flaws     affect packet and attribute parsing in the BGP daemon (including FlowSpec,     EVPN/VNC NLRI and MP_REACH_NLRI handling), the OSPF daemon (Traffic     Engineering, Segment Routing and Opaque LSA processing) and the babeld     daemon.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 8.4.4-1.1~deb12u2.

    For the stable distribution (trixie), these problems have been fixed in     version 10.3-3+deb13u1.

    We recommend that you upgrade your frr packages.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2024-27913)

Note that Nessus relies on the presence of the package as reported by the vendor.
