Ubuntu Security Notice 6590-1 - It was discovered that Xerces-C++ was not properly handling memory management operations when parsing XML data containing external DTDs, which could trigger a use-after-free error. If a user or automated system were tricked into processing a specially crafted XML document, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 22.04 LTS. It was discovered that Xerces-C++ was not properly performing bounds checks when processing XML Schema Definition files, which could lead to an out-of-bounds access via an HTTP request. If a user or automated system were tricked into processing a specially crafted XSD file, a remote attacker could possibly use this issue to cause a denial of service.

Firefox version 121 and Chrome version 120 may both suffer from a minor denial of service issue with file downloads.

Debian Linux Security Advisory 5602-1 - Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure. An exploit for CVE-2024-0519 exists in the wild.

Ubuntu Security Notice 6588-1 - Matthias Gerstner discovered that the PAM pam_namespace module incorrectly handled special files when performing directory checks. A local attacker could possibly use this issue to cause PAM to stop responding, resulting in a denial of service.

In some specific instances, the SurrealQL parser will attempt to recursively parse nested statements or idioms (i.e. nested `IF` and `RELATE` statements, nested basic idioms and nested access to attributes) without checking if the depth limit established by default or in the `SURREAL_MAX_COMPUTATION_DEPTH` environment variable is exceeded. This can lead to the stack overflowing when the nesting surpasses certain levels of depth. ### Impact An attacker that is authorized to run queries on a SurrealDB server may be able to run a query using the affected statements and idioms with very deep nesting in order to crash the server, leading to denial of service. ### Patches - Version 1.1.0 and later are not affected by this issue. ### Workarounds Concerned users unable to update may want to limit the ability of untrusted users to run arbitrary SurrealQL queries in the affected versions of SurrealDB. To limit the impact of the denial of service, SurrealDB administrators may also want to e...

The `ID`, `DB` and `NS` headers accepted by the SurrealDB HTTP REST API would fail to parse when containing some special characters. This would cause a panic which would crash the SurrealDB server, leading to denial of service. This issue only affects the SurrealDB binary; it does not affect the SurrealDB library. ### Impact An unauthenticated client may issue an HTTP request to the SurrealDB HTTP REST API containing one of the affected headers with values containing special characters in order to crash the SurrealDB server. This does not require the SurrealDB server to be running with any specific capabilities other than exposing the affected interface. ### Patches - Version 1.1.0 and later are not affected by this issue. ### Workarounds Concerned users unable to update may want to limit untrusted access to the SurrealDB HTTP REST API unless such access is required by the application. To limit the impact of the denial of service, SurrealDB administrators may also want to ensure...
