Description

This security bulletin contains information about 2 vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2014-0028)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

libvirt 1.1.1 through 1.2.0 allows context-dependent attackers to bypass the domain:getattr and connect:search_domains restrictions in ACLs and obtain sensitive domain object information via a request to the (1) virConnectDomainEventRegister and (2) virConnectDomainEventRegisterAny functions in the event registration API.


2) NULL pointer dereference (CVE-ID: CVE-2013-6436)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a guest in the shutdown status, as demonstrated by the "virsh memtune" command.
