Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU63787
Risk: Low
CVSSv3.1: 7.1 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-4206
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the target system.
The vulnerability exists due to integer overflow in the cursor_alloc() function in the QXL display device emulation in QEMU. A privileged user can crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.
MitigationUpdate the affected package qemu to the latest version.
