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.
