We’re thrilled to share that this year, the Microsoft Bounty Program has distributed $17 million to 344 security researchers from 59 countries, the highest total bounty awarded in the program’s history. In close collaboration with the Microsoft Security Response Center (MSRC), these security researchers have helped identify and resolve more than a thousand potential vulnerabilities, strengthening protections for Microsoft customers around the world.

### Summary The channel window adjust message of the SSH protocol is used to track the free space in the receive buffer of the other side of a channel. The current implementation takes the value from the message and adds it to an internal state value. This can result in a integer overflow. If the Rust code is compiled with overflow checks, it will panic. A malicious client can crash a server. ### Details According https://datatracker.ietf.org/doc/html/rfc4254#section-5.2, The value must not overflow. The incorrect handling is done in server/encrypted.rs and client/encrypted.rs in the handling of CHANNEL_WINDOW_ADJUST. ``` let amount = map_err!(u32::decode(&mut r))?; ... channel.recipient_window_size += amount; ``` It could be replaced with something like ``` if let Some(ref mut channel) = enc.channels.get_mut(&channel_num) { // rfc 4254: The window MUST NOT be increased above 2^32 - 1 bytes. new_size = channel.recipient_window...

A new Proofpoint report reveals how attackers are using Microsoft 365’s Direct Send and unsecured SMTP relays to…

A newly disclosed set of security flaws in NVIDIA's Triton Inference Server for Windows and Linux, an open-source platform for running artificial intelligence (AI) models at scale, could be exploited to take over susceptible servers. "When chained together, these flaws can potentially allow a remote, unauthenticated attacker to gain complete control of the server, achieving remote code execution

Security firm Point Wild has exposed a new malware campaign using malicious LNK files to install the REMCOS backdoor. This report details how attackers disguise files to gain full system control.

### Summary Nested imports of MaterialX files can lead to a crash via stack memory exhaustion, due to the lack of a limit on the "import chain" depth. ### Details The MaterialX [specification](https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/documents/Specification/MaterialX.Specification.md#mtlx-file-format-definition) supports importing other files by using `XInclude` tags. When parsing file imports, recursion is used to process nested files in the form of a tree with the root node being the first MaterialX files parsed. However, there is no limit imposed to the depth of files that can be parsed by the library, therefore, by building a sufficiently deep chain of MaterialX files one referencing the next, it is possible to crash the process using the MaterialX library via stack exhaustion. ### PoC This test is going to employ Windows UNC paths, in order to make the Proof Of Concept more realistic. In fact, by using windows network shares, an attacker would be able t...
