The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the…

An issue was discovered in OpenStack blazar-dashboard before 1.3.1, 2.0.0, and 3.0.0. A user allowed to access the Blazar dashboard in Horizon may trigger code execution on the Horizon host as the user the Horizon service runs under (because the Python eval function is used).…

OpenStack Mistral through 22.0.0 allows Arbitrary Remote Code Execution when the API is exposed. There are endpoints that allow code execution, which can lead to exfiltration of service credentials.

The trove service user in (1) Openstack deployment (aka crowbar-openstack) and (2) Trove Barclamp (aka barclamp-trove and crowbar-barclamp-trove) in the Crowbar Framework has a default password, which makes it easier for remote attackers to obtain access via unspecified vectors.

In OpenStack Zaqar before 22.0.2, WSGI transport mishandles the URL-Signature header. By sending a request with an empty URL-Signature header, an unauthenticated remote attacker who knows a target project's UUID may bypass both Keystone authentication and pre-signed URL…

A flaw was found in Openstack manilla owning a Ceph File system "share", which enables the owner to read/write any manilla share or entire file system. The vulnerability is due to a bug in the "volumes" plugin in Ceph Manager. This allows an attacker to compromise…

The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via a link-local source address.

In OpenStack Swift through 2.38.0, the proxy server Accept header parser contains a regular expression vulnerable to catastrophic backtracking (ReDoS). The "qdtext" pattern (?:[^"]|\\.)* allows an unauthenticated remote attacker to send a crafted Accept header that causes…

An issue was discovered in OpenStack keystonemiddleware 10.5 through 10.7 before 10.7.2, 10.8 and 10.9 before 10.9.1, and 10.10 through 10.12 before 10.12.1. The external_oauth2_token middleware fails to sanitize incoming authentication headers before processing OAuth 2.0…

An issue in OpenStack magnum yoga-eom version allows a remote attacker to execute arbitrary code via the cert_manager.py. component.

A privilege escalation vulnerability exists in the oslo.privsep functionality of OpenStack git master 05194e7618 and prior. Overly permissive functionality within tools leveraging this library within a container can lead increased privileges.

python-keystoneclient version 0.2.3 to 0.2.5 has middleware memcache signing bypass

python-keystoneclient version 0.2.3 to 0.2.5 has middleware memcache encryption bypass

OpenStack Magnum passes OpenStack credentials into the Heat templates creating its instances. While these should just be used for retrieving the instances' SSL certificates, they allow full API access, though and can be used to perform any API operation the user is authorized to…

A vulnerability was found in openstack-tripleo-heat-templates before version 8.0.2-40. When deployed using Director using default configuration, Opendaylight in RHOSP13 is configured with easily guessable default credentials.

An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack Swift through 2.15.1. The Swift object store and proxy server are saving (unhashed) tokens retrieved from the Swauth middleware authentication mechanism to a log file as part of a…

An issue was discovered in exception_wrapper.py in OpenStack Nova 13.x through 13.1.3, 14.x through 14.0.4, and 15.x through 15.0.1. Legacy notification exception contexts appearing in ERROR level logs may include sensitive information such as account passwords and authorization…

OpenStack Murano before 1.0.3 (liberty) and 2.x before 2.0.1 (mitaka), Murano-dashboard before 1.0.3 (liberty) and 2.x before 2.0.1 (mitaka), and python-muranoclient before 0.7.3 (liberty) and 0.8.x before 0.8.5 (mitaka) improperly use loaders inherited from yaml.Loader when…

A flaw was found in PackStack. A local user could exploit a symlink attack on a temporary file with a predictable name in the `/tmp` directory. This vulnerability allows the local user to overwrite arbitrary files on the system, potentially leading to system compromise or data…

OpenStack Object Storage (swift) before 1.7.0 uses the loads function in the pickle Python module unsafely when storing and loading metadata in memcached, which allows remote attackers to execute arbitrary code via a crafted pickle object.
