| HCL Hive is affected by an information disclosure vulnerability, which could lead to an attacker gathering sensitive information about the host environment. |
| Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. Prior to 8.0.5.2 and from 8.1 until 8.1.4.1, Active Storage's ActiveStorage::Previewer::VideoPreviewer, ActiveStorage::Analyzer::VideoAnalyzer, and ActiveStorage::Analyzer::AudioAnalyzer pass uploaded blob contents to FFmpeg without restricting the demuxer. A direct upload can retain a client-declared video/* or audio/* content type for an HLS playlist. FFmpeg content probing selects the hls demuxer, which opens attacker-named file:// segments when the blob is previewed or analyzed. Applications that accept untrusted uploads and generate video previews or analyze video or audio attachments can disclose a local media file readable by the application process when the attacker knows its path. This issue is fixed in versions 8.0.5.2 and 8.1.4.1. |
| Heap-based buffer overflow in Windows Biometric Service allows an authorized attacker to elevate privileges locally. |
| Description
A submitted topology carries two lists of blobstore keys, `dependency_jars` and `dependency_artifacts`,
which the client fills in after uploading the corresponding blobs. Nimbus performed no validation of their
contents on the submission path, yet acts on them in two places.
During cleanup of a finished topology, Nimbus deletes the keys named in those lists, and the deletion is
performed as the Nimbus subject, for which the blobstore short-circuits its ACL check. A submitter who
listed a key belonging to another topology, such as its `-stormjar.jar`, could therefore cause
that blob to be deleted when their own topology was cleaned up.
Separately, on acquiring leadership a Nimbus compares the dependency keys of all active topologies against
the blobstore contents and surrenders leadership if any is missing. A single key that does not exist, on a
single active topology, therefore causes every Nimbus to acquire leadership, surrender it and requeue
indefinitely, leaving the cluster without a leader and unable to schedule, clean up or accept submissions.
Mitigation
Upgrade to 3.1.0, where a submission is refused unless every entry in both lists is a dependency blob key
and exists in the blobstore.
Note that this validates new submissions only; a topology stored by an affected version with an invalid list
is unaffected by the upgrade. An operator whose cluster is failing to retain a leader should inspect the
Nimbus log for the dependency keys reported as missing and remove or resubmit the topology naming them.
Users who cannot upgrade immediately should restrict topology submission to trusted principals.

This issue was discovered by rzo1 while investigating an unrelated blobstore defect. |
| On affected platforms running Arista EOS with Dynamic Host Configuration Protocol (DHCP) relay/snooping configured with the information option (Option 82), or with the DHCP server configured with match criteria based on the information option, an unauthenticated attacker connected to a client-facing VLAN(s) where the relay is configured can send a specially crafted packet that causes the DHCP Relay service to restart. |
| Adobe Experience Manager is affected by an Improper Input Validation vulnerability that could result in a Security feature bypass. A low-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized limited read and write access. Exploitation of this issue does not require user interaction. |
| PostgreSQL's optimized statistics on a table are visible as long as you have SELECT privilege on said table. A masked role can therefore read a limited subset of the data through the statistics view's histograms and mcvs. The vulnerability is resolved in PostgreSQL Anonymizer 3.3.0 and later versions. |
| PostgreSQL restricts acces to the salt and shift via the `SHOW` command for users not member of `pg_read_all_settings`. But they are visible in `pg_db_role_setting` or `pg_roles` if they were set on the database, user or both. PostgreSQL Anonymizer's documentation recommends to use ALTER DATABASE / ALTER ROLE for the salt. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions. |
