MEDIUM Privileges required
SINGLE Confidentiality impact
NONE Integrity impact

PARTIAL Summary
OpenStack Compute (Nova) Folsom, Grizzly, and earlier, when using Apache Qpid for the RPC backend, does not properly handle errors that occur during messaging, which allows remote attackers to cause a denial of service (connection pool consumption), as demonstrated using multiple requests that send long strings to an instance console and retrieving the console log.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-2000-1.NASL description It was discovered that Nova did not properly enforce the is_public property when determining flavor access. An authenticated attacker could exploit this to obtain sensitive information in private flavors. This issue only affected Ubuntu 12.10 and 13.10. (CVE-2013-2256, CVE-2013-4278) Grant Murphy discovered that Nova would allow XML entity processing. A remote unauthenticated attacker could exploit this using the Nova API to cause a denial of service via resource exhaustion. This issue only affected Ubuntu 13.10. (CVE-2013-4179) Vishvananda Ishaya discovered that Nova inefficiently handled network security group updates when Nova was configured to use nova-network. An authenticated attacker could exploit this to cause a denial of service. (CVE-2013-4185) Jaroslav Henner discovered that Nova did not properly handle certain inputs to the instance console when Nova was configured to use Apache Qpid. An authenticated attacker could exploit this to cause a denial of service on the compute node running the instance. By default, Ubuntu uses RabbitMQ instead of Qpid. (CVE-2013-4261).
