| From the Red Hat advisory:
It was found that the fixes for CVE-2013-1664 and CVE-2013-1665, released
via RHSA-2013:0657, did not fully correct the issues in the Extensible
Markup Language (XML) parser used by Nova. A remote attacker could use
this flaw to send a specially-crafted request to a Nova API, causing
Nova to consume an excessive amount of CPU and memory, or possibly crash.
(CVE-2013-4179)
A denial of service flaw was found in the way Nova handled network source
security group policy updates. An authenticated user could send a large
number of server creation operations, causing nova-network to become
unresponsive. (CVE-2013-4185)
An information disclosure flaw and a resource limit bypass were found in
the way Nova handled virtual hardware templates (flavors). These allowed
tenants to show and boot other tenants' flavors and bypass resource limits
enforced via the os-flavor-access:is_public property. (CVE-2013-2256)
It was discovered that, in some configurations, certain messages in
console-log could cause nova-compute to become unresponsive, resulting in a
denial of service. (CVE-2013-4261) |
