### Advisory title: Field-level security issue with .keyword fields ### Affected versions: OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1 ### Patched versions: OpenSearch 1.3.8 and 2.5.0 ### Impact: There is an issue in the implementation of field-level security (FLS) and field masking where rules written to explicitly exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword fields. This issue is only present for authenticated users with read access to the indexes containing the restricted fields. ### Workaround: FLS rules that use explicit exclusions can be written to grant explicit access instead. Policies authored in this way are not subject to this issue. ### Patches: OpenSearch versions 1.3.8 and 2.5.0 contain a fix for this issue. ### For more information: If you have any questions or comments about this advisory, please contact AWS/Amazon Security via our issue reporting page (https://aws.amazon.com/security/vulnerability-reporting/)...

### Advisory title: Issue with whitespace in JWT roles ### Affected versions: OpenSearch 1.0.0-1.3.7 and 2.0.0-2.4.1 ### Patched versions: OpenSearch 1.3.8 and 2.5.0 ### Impact: OpenSearch uses JWTs to store role claims obtained from the Identity Provider (IdP) when the authentication backend is SAML or OpenID Connect. There is an issue in how those claims are processed from the JWTs where the leading and trailing whitespace is trimmed, allowing users to potentially claim roles they are not assigned to if any role matches the whitespace-stripped version of the roles they are a member of. This issue is only present for authenticated users, and it requires either the existence of roles that match, not considering leading/trailing whitespace, or the ability for users to create said matching roles. In addition, the Identity Provider must allow leading and trailing spaces in role names. ### Patches: OpenSearch versions 1.3.8 and 2.5.0 contain a fix for this issue. ### For more informa...

Ubuntu Security Notice 5813-1 - It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.
