Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU69594

Risk: Medium

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

CVE-ID: CVE-2022-39316

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in ZGFX decoder. A malicious server can trick a FreeRDP based client to read out of bound data and try to decode it.

Successful exploitation of the vulnerability may allows remote code execution.

Mitigation

Update the affected package freerdp to the latest version.
