CVE-2015-7713

OpenStack Compute (Nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) do not properly apply security group changes, which allows remote attackers to bypass intended restriction by leveraging an instance that was running when the change was made.

George Shuklin discovered that OpenStack Nova incorrectly handled the migration process. A remote authenticated user could use this issue to consume resources, resulting in a denial of service. (CVE-2015-3241)

George Shuklin and Tushar Patil discovered that OpenStack Nova incorrectly handled deleting instances. A remote authenticated user could use this issue to consume disk resources, resulting in a denial of service. (CVE-2015-3280)

It was discovered that OpenStack Nova incorrectly limited qemu-img calls. A remote authenticated user could use this issue to consume resources, resulting in a denial of service. (CVE-2015-5162)

Matthew Booth discovered that OpenStack Nova incorrectly handled snapshots. A remote authenticated user could use this issue to read arbitrary files. (CVE-2015-7548)

Sreekumar S. and Suntao discovered that OpenStack Nova incorrectly applied security group changes. A remote attacker could possibly use this issue to bypass intended restriction changes by leveraging an instance that was running when the change was made. (CVE-2015-7713)

Matt Riedemann discovered that OpenStack Nova incorrectly handled logging. A local attacker could possibly use this issue to obtain sensitive information from log files. (CVE-2015-8749)

Matthew Booth discovered that OpenStack Nova incorrectly handled certain qcow2 headers. A remote authenticated user could possibly use this issue to read arbitrary files. (CVE-2016-2140)
