CVSS v3.1 |
| Wasmtime is a runtime for WebAssembly. Wasmtime 37.0.0 and 37.0.1 have memory leaks in the C/C++ API when using bindings for the `anyref` or `externref` WebAssembly values. This is caused by a regression introduced during the development of 37.0.0 and all prior versions of Wasmtime are unaffected. If `anyref` or `externref` is not used in the C/C++ API then embeddings are also unaffected by the leaky behavior. The `wasmtime` Rust crate is unaffected by this leak.
Development of Wasmtime 37.0.0 included a refactoring in Rust of changing the old `ManuallyRooted<T>` type to a new `OwnedRooted<T>` type. This change was integrated into Wasmtime's C API but left the C API in a state which had memory leaks. Additionally the new ownership semantics around this type were not reflected into the C++ API, making it leak-prone. A short version of the change is that previously `ManuallyRooted<T>`, as the name implies, required manual calls to an "unroot" operation. If this was forgotten then the memory was still cleaned up when the `wasmtime_store_t` itself was destroyed eventually. Documentation of when to "unroot" was sparse and there were already situations prior to 37.0.0 where memory would be leaked until the store was destroyed anyway. All memory, though, was always bound by the store, and destroying the store would guarantee that there were no memory leaks.
In migrating to `OwnedRooted<T>` the usage of the type in Rust changed. A manual "unroot" operation is no longer required and it happens naturally as a destructor of the `OwnedRooted<T>` type in Rust itself. These new resource ownership semantics were not fully integrated into the preexisting semantics of the C/C++ APIs in Wasmtime. A crucial distinction of `OwnedRooted<T>` vs `ManuallyRooted<T>` is that the `OwnedRooted<T>` type allocates host memory outside of the store. This means that if an `OwnedRooted<T>` is leaked then destroying a store does not release this memory and it's a permanent memory leak on the host.
This led to a few distinct, but related, issues arising: A typo in the `wasmtime_val_unroot` function in the C API meant that it did not actually unroot anything. This meant that even if embedders faithfully call the function then memory will be leaked. If a host-defined function returned a `wasmtime_{externref,anyref}_t` value then the value was never unrooted. The C/C++ API no longer has access to the value and the Rust implementation did not unroot. This meant that any values returned this way were never unrooted. The goal of the C++ API of Wasmtime is to encode automatic memory management in the type system, but the C++ API was not updated when `OwnedRooted<T>` was added. This meant that idiomatic usage of the C++ API would leak memory due to a lack of destructors on values.
These issues have all been fixed in a 37.0.2 release of Wasmtime. The implementation of the C and C++ APIs have been updated accordingly and respectively to account for the changes of ownership here. For example `wasmtime_val_unroot` has been fixed to unroot, the Rust-side implementation of calling an embedder-defined function will unroot return values, and the C++ API now has destructors on the `ExternRef`, `AnyRef`, and `Val` types. These changes have been made to the 37.0.x release branch in a non-API-breaking fashion. Changes to the 38.0.0 release branch (and `main` in the Wasmtime repository) include minor API updates to better accommodate the API semantic changes. The only known workaround at this time is to avoid using `externref` and `anyref` in the C/C++ API of Wasmtime. If avoiding those types is not possible then it's required for users to update to mitigate the leak issue. |
| An issue WebKul Bagisto v.2.3.6 allows a remote attacker to execute arbitrary code via the Cart/Checkout API endpoint, specifically, the price calculation logic fails to validate quantity inputs properly. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix vport QoS cleanup on error
When enabling vport QoS fails, the scheduling node was never freed,
causing a leak.
Add the missing free and reset the vport scheduling node pointer to
NULL. |
| A remote code execution vulnerability exists in the way that the MSHTML engine inproperly validates input, aka "MSHTML Engine Remote Code Execution Vulnerability." This affects Microsoft Office, Microsoft Office Word Viewer, Internet Explorer 9, Internet Explorer 11, Microsoft Excel Viewer, Internet Explorer 10, Office 365 ProPlus. |
| In the Linux kernel, the following vulnerability has been resolved:
media: s5p_cec: limit msg.len to CEC_MAX_MSG_SIZE
I expect that the hardware will have limited this to 16, but just in
case it hasn't, check for this corner case. |
| Opencast is free and open source software for automated video capture and distribution. First noticed in Opencast 13 and 14, Opencast's Elasticsearch integration may generate syntactically invalid Elasticsearch queries in relation to previously acceptable search queries. From Opencast version 11.4 and newer, Elasticsearch queries are retried a configurable number of times in the case of error to handle temporary losses of connection to Elasticsearch. These invalid queries would fail, causing the retry mechanism to begin requerying with the same syntactically invalid query immediately, in an infinite loop. This causes a massive increase in log size which can in some cases cause a denial of service due to disk exhaustion.
Opencast 13.10 and Opencast 14.3 contain patches which address the base issue, with Opencast 16.7 containing changes which harmonize the search behaviour between the admin UI and external API. Users are strongly recommended to upgrade as soon as possible if running versions prior to 13.10 or 14.3. While the relevant endpoints require (by default) `ROLE_ADMIN` or `ROLE_API_SERIES_VIEW`, the problem queries are otherwise innocuous. This issue could be easily triggered by normal administrative work on an affected Opencast system. Those who run a version newer than 13.10 and 14.3 and see different results when searching in their admin UI vs your external API or LMS, may resolve the issue by upgrading to 16.7. No known workarounds for the vulnerability are available. |
| OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. Starting in version 0.37.0 and prior to version 0.46.0, the grpc Unary Server Interceptor out of the box adds labels `net.peer.sock.addr` and `net.peer.sock.port` that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent. An attacker can easily flood the peer address and port for requests. Version 0.46.0 contains a fix for this issue. As a workaround to stop being affected, a view removing the attributes can be used. The other possibility is to disable grpc metrics instrumentation by passing `otelgrpc.WithMeterProvider` option with `noop.NewMeterProvider`. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmem: core: fix cleanup after dev_set_name()
If dev_set_name() fails, we leak nvmem->wp_gpio as the cleanup does not
put this. While a minimal fix for this would be to add the gpiod_put()
call, we can do better if we split device_register(), and use the
tested nvmem_release() cleanup code by initialising the device early,
and putting the device.
This results in a slightly larger fix, but results in clear code.
Note: this patch depends on "nvmem: core: initialise nvmem->id early"
and "nvmem: core: remove nvmem_config wp_gpio".
[Srini: Fixed subject line and error code handing with wp_gpio while applying.] |

| A vulnerability in the Remote Access VPN (RAVPN) service of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) of the RAVPN service.
This vulnerability is due to resource exhaustion. An attacker could exploit this vulnerability by sending a large number of VPN authentication requests to an affected device. A successful exploit could allow the attacker to exhaust resources, resulting in a DoS of the RAVPN service on the affected device. Depending on the impact of the attack, a reload of the device may be required to restore the RAVPN service. Services that are not related to VPN are not affected.
Cisco Talos discussed these attacks in the blog post Large-scale brute-force activity targeting VPNs, SSH services with commonly used login credentials. |
| A vulnerability in the web-based management interface of Cisco Small Business Routers RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary commands on an affected device.
This vulnerability is due to improper validation of user input within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to gain root-level privileges and access unauthorized data. To exploit this vulnerability, an attacker would need to have valid administrative credentials on the affected device.
Cisco has not and will not release software updates that address this vulnerability. However, administrators may disable the affected feature as described in the Workarounds ["#workarounds"] section.
