Description

This security bulletin contains information about 15 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2022-26126)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in isis_nb_notifications.c. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Buffer overflow (CVE-ID: CVE-2022-26127)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the babel_packet_examin() function in babeld/message.c. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Buffer overflow (CVE-ID: CVE-2022-26128)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the babel_packet_examin() function in babeld/message.c. A remote attacker can send specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Buffer overflow (CVE-ID: CVE-2022-26129)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the parse_hello_subtlv(), parse_ihu_subtlv(), and parse_update_subtlv() functions in babeld/message.c. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


5) Out-of-bounds read (CVE-ID: CVE-2022-37032)

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.


6) Use-after-free (CVE-ID: CVE-2022-37035)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing BGP packets within the bgp_notify_send_with_data() and bgp_process_packet() function in bgp_packet.c. A remote attacker can send specially crafted BGP packets to the affected daemon, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


7) Input validation error (CVE-ID: CVE-2023-31490)

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_psid_sub() function in bgpd. A remote attacker can pass specially crafted input to the server and perform a denial of service (DoS) attack.


8) Input validation error (CVE-ID: CVE-2023-38406)

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 in bgpd/bgp_flowspec.c. A remote attacker can send specially crafted input to the application and perform a denial of service (DoS) attack.


9) Out-of-bounds read (CVE-ID: CVE-2023-38407)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition during labeled unicast parsing in bgpd/bgp_label.c. A remote attacker can send specially crafted input to the application, trigger an out-of-bounds read error and crash the daemon.


10) Input validation error (CVE-ID: CVE-2023-46752)

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 when processing MP_REACH_NLRI data. A remote attacker can send specially crafted input to the application and perform a denial of service (DoS) attack.


11) Input validation error (CVE-ID: CVE-2023-46753)

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 when processing BGP UPDATE message without mandatory attributes. A remote attacker can send specially crafted input to the application and perform a denial of service (DoS) attack.


12) Input validation error (CVE-ID: CVE-2023-47234)

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 when processing a crafted BGP UPDATE message with a MP_UNREACH_NLRI attribute and additional NLRI data (that lacks mandatory path attributes). A remote attacker can send specially crafted messages to the daemon and perform a denial of service (DoS) attack.


13) Input validation error (CVE-ID: CVE-2023-47235)

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 when a malformed BGP UPDATE message with an EOR is processed. A remote attacker can send specially crafted input to the application and perform a denial of service (DoS) attack.


14) Buffer overflow (CVE-ID: CVE-2024-31948)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error when parsing Prefix SID attribute in a BGP UPDATE packet. A remote attacker can send specially crafted packets to the application, trigger memory corruption and crash the bgpd daemon.


15) Input validation error (CVE-ID: CVE-2023-38802)

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 when processing BGP update data with a corrupted attribute 23 (Tunnel Encapsulation). A remote attacker can send specially crafted BGP update data to the application and perform a denial of service (DoS) attack.
