| Issue summary: Calling the OpenSSL API function SSL_free_buffers may cause
memory to be accessed that was previously freed in some situations
Impact summary: A use after free can have a range of potential consequences such
as the corruption of valid data, crashes or execution of arbitrary code.
However, only applications that directly call the SSL_free_buffers function are
affected by this issue. Applications that do not call this function are not
vulnerable. Our investigations indicate that this function is rarely used by
applications.
The SSL_free_buffers function is used to free the internal OpenSSL buffer used
when processing an incoming record from the network. The call is only expected
to succeed if the buffer is not currently in use. However, two scenarios have
been identified where the buffer is freed even when still in use.
The first scenario occurs where a record header has been received from the
network and processed by OpenSSL, but the full record body has not yet arrived.
In this case calling SSL_free_buffers will succeed even though a record has only
been partially processed and the buffer is still in use.
The second scenario occurs where a full record containing application data has
been received and processed by OpenSSL but the application has only read part of
this data. Again a call to SSL_free_buffers will succeed even though the buffer
is still in use.
While these scenarios could occur accidentally during normal operation a
malicious attacker could attempt to engineer a stituation where this occurs.
We are not aware of this issue being actively exploited.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. |

| A vulnerability was found in Dromara Northstar up to 7.3.5. It has been rated as critical. Affected by this issue is the function preHandle of the file northstar-main/src/main/java/org/dromara/northstar/web/interceptor/AuthorizationInterceptor.java of the component Path Handler. The manipulation of the argument Request leads to improper access controls. The attack may be launched remotely. Upgrading to version 7.3.6 is able to address this issue. The patch is identified as 8d521bbf531de59b09b8629a9cbf667870ad2541. It is recommended to upgrade the affected component. |
| A vulnerability classified as problematic was found in Sapido RB-1802 1.0.32. This vulnerability affects unknown code of the file urlfilter.asp of the component URL Filtering Page. The manipulation of the argument URL address leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/vfio-ap: fix memory leak in vfio_ap device driver
The device release callback function invoked to release the matrix device
uses the dev_get_drvdata(device *dev) function to retrieve the
pointer to the vfio_matrix_dev object in order to free its storage. The
problem is, this object is not stored as drvdata with the device; since the
kfree function will accept a NULL pointer, the memory for the
vfio_matrix_dev object is never freed.
Since the device being released is contained within the vfio_matrix_dev
object, the container_of macro will be used to retrieve its pointer. |

| An attacker can arbitrarily craft malicious DDS Participants (or ROS 2 Nodes) with valid certificates to compromise and get full control of the attacked secure DDS databus system by exploiting vulnerable attributes in the configuration of PKCS#7 certificate’s validation. This is caused by a non-compliant implementation of permission document verification used by some DDS vendors. Specifically, an improper use of the OpenSSL PKCS7_verify function used to validate S/MIME signatures. |

| ### Impact
When this library is used to deserialize messagepack data from an untrusted source, there is a risk of a denial of service attack by an attacker that sends data contrived to produce hash collisions, leading to large CPU consumption disproportionate to the size of the data being deserialized.
This is similar to [a prior advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf), which provided an inadequate fix for the hash collision part of the vulnerability.
### Patches
The following steps are required to mitigate this risk.
1. Upgrade to a version of the library where a fix is available.
1. Review the steps in [this previous advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf) to ensure you have your application configured for untrusted data.
### Workarounds
If upgrading MessagePack to a patched version is not an option for you, you may apply a manual workaround as follows:
1. Declare a class that derives from `MessagePackSecurity`.
2. Override the `GetHashCollisionResistantEqualityComparer<T>` method to provide a collision-resistant hash function of your own and avoid calling `base.GetHashCollisionResistantEqualityComparer<T>()`.
3. Configure a `MessagePackSerializerOptions` with an instance of your derived type by calling `WithSecurity` on an existing options object.
4. Use your custom options object for all deserialization operations. This may be by setting the `MessagePackSerializer.DefaultOptions` static property, if you call methods that rely on this default property, and/or by passing in the options object explicitly to any `Deserialize` method.
