Debian dla-3797 : frr - security update

critical Nessus Plugin ID 194417

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3797 advisory.

- 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-2022-26125)

- 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-2022-26126)

- 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-2022-26127)

- 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-2022-26128)

- 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-2022-26129)

- 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-2022-37035)

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

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

- An issue was discovered in FRRouting FRR through 9.0.1. It mishandles malformed MP_REACH_NLRI data, leading to a crash. (CVE-2023-46752)

- 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-2023-46753)

- 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-2023-47234)

- 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-2023-47235)

- 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-2024-31948)

- 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-2024-31949)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the frr packages.
