Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Out-of-bounds write

EUVDB-ID: #VU76194

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-25564

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists due to a boundary in the ntlm_str_convert() function error when decoding UTF16 strings. A remote attacker can send specially crafted NTLM request to the application, trigger an out-of-bounds write error and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
