Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Resource management error

EUVDB-ID: #VU42517

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2013-4153

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Double free vulnerability in the qemuAgentGetVCPUs function in qemu/qemu_agent.c in libvirt 1.0.6 through 1.1.0 allows remote attackers to cause a denial of service (daemon crash) via a cpu count request, as demonstrated by the "virsh vcpucount dom --guest" command.

Mitigation

Install update from vendor's website.

2) Buffer overflow

EUVDB-ID: #VU42522

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
