Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU66470

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-26129

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.
