CVE-2015-5162

OpenStack Cinder, Glance, and Nova contain Uncontrolled Resource Consumption

The image parser in OpenStack Cinder prior to 7.0.2, and 8.0.0 and above, prior to 9.0.0; Glance prior to 14.00; and Nova prior to 12.0.4 does not properly limit qemu-img calls, which might allow attackers to cause a denial of service (memory and disk consumption) via a crafted disk image. This issue is patched in Cinder 7.0.2 and 9.0.0; Glance 14.0.0; and Nova 12.0.4

Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.

CVE-2015-5162 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (7.0.2, 9.0.0, 14.0.0, 12.0.4); upgrading removes the vulnerable code path.

1. What is CVE-2015-5162? CVE-2015-5162 is a high-severity uncontrolled resource consumption vulnerability in cinder (pip), affecting versions < 7.0.2. It is fixed in 7.0.2, 9.0.0, 14.0.0, 12.0.4. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.
2. How severe is CVE-2015-5162? CVE-2015-5162 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2015-5162?
   • cinder (pip) (versions < 7.0.2)
   • glance (pip) (versions < 14.0.0)
   • nova (pip) (versions < 12.0.4)
4. Is there a fix for CVE-2015-5162? Yes. CVE-2015-5162 is fixed in 7.0.2, 9.0.0, 14.0.0, 12.0.4. Upgrade to this version or later.
5. Is CVE-2015-5162 exploitable, and should I be worried? Whether CVE-2015-5162 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2015-5162 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2015-5162?
   • Upgrade cinder to 7.0.2 or later
   • Upgrade cinder to 9.0.0 or later
   • Upgrade glance to 14.0.0 or later
   • Upgrade nova to 12.0.4 or later
