| Heap-based buffer overflow in Microsoft Standard XPS allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Remote Desktop Licensing Service allows an authorized attacker to elevate privileges over a network. |
| Use after free in Windows License Manager allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows USB Audio Class driver (usbaudio.sys) allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Cloud Files Mini Filter Driver allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Device Association Service allows an authorized attacker to elevate privileges over a network. |
| Heap-based buffer overflow in Microsoft JScript allows an unauthorized attacker to execute code over a network. |
| Heap-based buffer overflow in Microsoft Standard XPS allows an authorized attacker to elevate privileges over a network. |
| Use after free in Windows DNS allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Kernel allows an authorized attacker to elevate privileges over a network. |
| Double free in Windows Registry allows an authorized attacker to elevate privileges over a network. |

| Stack-based buffer overflow in Windows DHCP Client allows an unauthorized attacker to elevate privileges over an adjacent network. |
| Heap-based buffer overflow in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to elevate privileges locally. |
| Numeric truncation error in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Biometric Service allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Modern Device Management (MDM) allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Biometric Service allows an authorized attacker to elevate privileges locally. |
| A flaw was found in GIMP's PSP (Paint Shop Pro) file loader. When processing a compressed selection channel, a heap-based buffer overflow can occur due to a mismatch between the allocated buffer size and the amount of data decompressed. A remote attacker could exploit this vulnerability by crafting a malicious PSP file. Opening this file in GIMP could lead to a crash or arbitrary code execution. |
| Description
Nimbus validated `topology.blobstore.map` against the calling subject at submission time only. The rebalance
operation accepts configuration overrides and stripped a small set of keys from them, but never re-ran that
validation, so a caller authorised to rebalance a topology could introduce a blobstore map entry naming a
blob whose ACL does not grant them access. Supervisors localise whatever key the map names, placing the
blob's contents into the topology's working directory.
The same advisory covers `listBlobs`, which performed no authorization check and passed no subject, unlike
the neighbouring `getBlobMeta` and `beginBlobDownload` operations. It therefore returned every key in the
blobstore to any caller able to reach the Nimbus Thrift port, which provides the key names that make the
above practical. On its own the disclosure is metadata only.
Mitigation
Upgrade to 3.1.0, where rebalance configuration overrides are validated exactly as submission-time
configuration is, against the rebalancing caller, and where `listBlobs` applies the configured
authorization.
Users who cannot upgrade immediately should restrict rebalance rights to trusted principals, keeping in mind
that membership of a topology's `topology.users` or `topology.groups` confers them.
