Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Information exposure through microarchitectural state after transient execution
EUVDB-ID: #VU79262
Risk: Medium
CVSSv4.0: 2.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-40982
CWE-ID:
CWE-1342 - Information Exposure through Microarchitectural State after Transient Execution
Exploit availability: No
DescriptionThe vulnerability allows a malicious guest to escalate privileges on the system.
The vulnerability exists due to the way data is shared between threads whereby the AVX GATHER instructions on Intel processors can forward the content of stale vector registers to dependent instructions. A malicious guest can infer data from different contexts on the same core and execute arbitrary code with elevated privileges.
Update the affected package xen to the latest version.

4) Resource management error
EUVDB-ID: #VU80924
Risk: Low
CVSSv4.0: 4.8 [CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-34322
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a malicious guest to escalate privileges on the system.
The vulnerability exists due to improper management of internal resources when running PV guests in shadow paging mode. A malicious guest can run a specially crafted application on the system that causes shortage of memory in the associated with the domain shadow pool and forces Xen to tear down page tables. This can result in memory leak, denial of service or privilege escalation.
The vulnerability can be exploited by 64-bit PV guests on x86 systems.
Update the affected package xen to the latest version.
