Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU57585
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-41159
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing /gt:rpc connections. A remote server can send specially crafted data to the client, trigger an out-of-bounds write and execute arbitrary code on the target system.
MitigationUpdate the affected package freerdp to the latest version.
