    Multiple security vulnerabilities were found in frr, the FRRouting suite     of internet protocols. Maliciously constructed Border Gateway Protocol     (BGP) packages or corrupted tunnel attributes may cause a denial of service     (application crash) which could be exploited by a remote attacker.

    For Debian 10 buster, these problems have been fixed in version     7.5.1-1.1+deb10u1.

    We recommend that you upgrade your frr packages.

    For the detailed security status of frr please refer to     its security tracker page at:

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-2024:0036 advisory.

    Package updates are available for TencentOS Server 4 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-2023-38802:
    FRRouting FRR 7.5.1 through 9.0 and Pica8 PICOS 4.3.3.2 allow a remote attacker to cause a denial of     service via a crafted BGP update with a corrupted attribute 23 (Tunnel Encapsulation).

    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-2023-41359:
    An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds read in     bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the availability of two bytes during     AIGP validation.

    CVE-2023-41360:
    An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c can read the initial byte of the     ORF header in an ahead-of-stream situation.

    CVE-2023-41361:
    An issue was discovered in FRRouting FRR 9.0. bgpd/bgp_open.c does not check for an overly large length of     the rcv software version.

    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:
    An issue was discovered in FRRouting FRR through 9.0.1. It mishandles malformed MP_REACH_NLRI data,     leading to a crash.

    CVE-2023-46753:
    An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur for a crafted BGP UPDATE message     without mandatory attributes, e.g., one with only an unknown transit attribute.

    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.
