Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU59046
Risk: Low
CVSSv4.0: 7.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear]
CVE-ID: CVE-2021-4009
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the ProcXFixesCreatePointerBarrier() function in the XFixes extension. A local user can send a specially crafted CreatePointerBarrier request, trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
Update the affected package xorg-x11-server to the latest version.
