    Several vulnerabilities have been found in frr, the FRRouting suite of     internet protocols. An attacker could craft packages to potentially trigger     those effects: buffer overflows with the possibility to gain remote code     execution, buffer overreads, crashes or trick the software to enter an     infinite loop.

    CVE-2022-26125

        Buffer overflow vulnerabilities exist in FRRouting through 8.1.0 due to         wrong checks on the input packet length in isisd/isis_tlvs.c.

    CVE-2022-26126

        Buffer overflow vulnerabilities exist in FRRouting through 8.1.0 due to         the use of strdup with a non-zero-terminated binary string in         isis_nb_notifications.c.

    CVE-2022-26127

        A buffer overflow vulnerability exists in FRRouting through 8.1.0 due to         missing a check on the input packet length in the babel_packet_examin         function in babeld/message.c.

    CVE-2022-26128

        A buffer overflow vulnerability exists in FRRouting through 8.1.0 due to         a wrong check on the input packet length in the babel_packet_examin         function in babeld/message.c.

    CVE-2022-26129

        Buffer overflow vulnerabilities exist in FRRouting through 8.1.0 due to         wrong checks on the subtlv length in the functions, parse_hello_subtlv,         parse_ihu_subtlv, and parse_update_subtlv in babeld/message.c.

    CVE-2022-37035

        An issue was discovered in bgpd in FRRouting (FRR) 8.3. In         bgp_notify_send_with_data() and bgp_process_packet() in bgp_packet.c,         there is a possible use-after-free due to a race condition. This could         lead to Remote Code Execution or Information Disclosure by sending         crafted BGP packets. User interaction is not needed for exploitation.

    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-2023-46752

        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-2023-47234

        An issue was discovered in bgpd in FRRouting (FRR) 8.3. In         bgp_notify_send_with_data() and bgp_process_packet() in bgp_packet.c,         there is a possible use-after-free due to a race condition. This could         lead to Remote Code Execution or Information Disclosure by sending         crafted BGP packets. User interaction is not needed for exploitation.

    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.

    CVE-2024-31948

        In FRRouting (FRR) through 9.1, an attacker using a malformed Prefix SID         attribute in a BGP UPDATE packet can cause the bgpd daemon to crash.

    CVE-2024-31949

        In FRRouting (FRR) through 9.1, an infinite loop can occur when         receiving a MP/GR capability as a dynamic capability because malformed         data results in a pointer not advancing.

    CVE-2024-44070

        An issue was discovered in FRRouting (FRR) through 10.1. bgp_attr_encap         in bgpd/bgp_attr.c does not check the actual remaining stream length         before taking the TLV value.

    For Debian 11 bullseye, these problems have been fixed in version     7.5.1-1.1+deb11u3.

    We recommend that you upgrade your frr packages.
