Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Reachable Assertion
EUVDB-ID: #VU81895
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-34323
CWE-ID:
CWE-617 - Reachable Assertion
Exploit availability: No
DescriptionThe vulnerability allows a remote guest to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion when handling negative quota values in C Xenstored. A malicious guest can craft a transaction that forces C Xenstored to check quota value and perform a denial of service attack.
Update the affected package xen to the latest version.
