Redhat: >> Openstack >> 14 Security Vulnerabilities
A flaw was found in Hibernate ORM in versions before 5.3.18, 5.4.18 and 5.5.0.Beta1. A SQL injection in the implementation of the JPA Criteria API can permit unsanitized literals when a literal is used in the SELECT or GROUP BY parts of the query. This flaw could allow an attacker to access unauthorized information or possibly conduct further attacks.

A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.

An information-exposure vulnerability was discovered where openstack-mistral's undercloud log files containing clear-text information were made world readable. A malicious system user could exploit this flaw to access sensitive user information.

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.

Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

An issue was discovered in OpenStack Nova before 17.0.12, 18.x before 18.2.2, and 19.x before 19.0.2. If an API request from an authenticated user ends in a fault condition due to an external exception, details of the underlying environment may be leaked in the response, and could include sensitive configuration or other data.

A flaw was discovered in the way Ansible templating was implemented in versions before 2.6.18, 2.7.12 and 2.8.2, causing the possibility of information disclosure through unexpected variable substitution. By taking advantage of unintended variable substitution the content of any variable may be disclosed.

A vulnerability was found in openstack-ironic-inspector all versions excluding 5.0.2, 6.0.3, 7.2.4, 8.0.3 and 8.2.1. A SQL-injection vulnerability was found in openstack-ironic-inspector's node_cache.find_node(). This function makes a SQL query using unfiltered data from a server reporting inspection results (by a POST to the /v1/continue endpoint). Because the API is unauthenticated, the flaw could be exploited by an attacker with access to the network on which ironic-inspector is listening. Because of how ironic-inspector uses the query results, it is unlikely that data could be obtained. However, the attacker could pass malicious data and create a denial of service.

A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By carefully corrupting a hyperloglog using the SETRANGE command, an attacker could trick Redis interpretation of dense HLL encoding to write up to 3 bytes beyond the end of a heap-allocated buffer.

A stack-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By corrupting a hyperloglog using the SETRANGE command, an attacker could cause Redis to perform controlled increments of up to 12 bytes past the end of a stack-allocated buffer.
