Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2022-26125)

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

The vulnerability exists due to a boundary error when handling packets within isisd/isis_tlvs.c. A remote attacker can send specially crafted packets 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-2022-26126)

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.


3) 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.


4) 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.


5) 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.
