CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an error when handling attribute length in BPG packets. A remote attacker can send a malformed BGP UPDATE packet from a connected peer and trigger transmission of up to a few thousand unintended bytes.
2) Out-of-bounds read (CVE-ID: CVE-2022-37032)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when processing BGP messages. A remote attacker can send specially crafted BGP messages to the system, trigger an out-of-bounds read error and read contents of memory on the system or crash the BGP daemon.
3) Input validation error (CVE-ID: CVE-2024-44070)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the bgp_attr_encap() function in bgpd/bgp_attr.c. A remote attacker can send specially crafted BGP traffic to the daemon and perform a denial of service (DoS) attack.
