supplying third party library with untrusted user input may lead to remote code execution
CVE: CVE-2021-32802
Component: nextcloud
CVSS v3: 9.8/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Release date: 2021-09-08T00:00:00+00:00

Nextcloud server is an open source, self hosted personal cloud. Nextcloud supports rendering image previews for user provided file content. For some image types, the Nextcloud server was invoking a third-party library that wasn't suited for untrusted user-supplied content. There are several security concerns with passing user-generated content to this library, such as Server-Side-Request-Forgery, file disclosure or potentially executing code on the system. The risk depends on your system configuration and the installed library version. It is recommended that the Nextcloud Server is upgraded to 20.0.12, 21.0.4 or 22.1.0. These versions do not use this library anymore. As a workaround users may disable previews by setting `enable_previews` to `false` in `config.php`.

Statement: Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery.

Remote Page Deduplication Attacks
CVE: CVE-2021-3714
Component: kernel
CWE: CWE-200
Severity: Moderate
CVSS v3: 5.8/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
Release date: 2021-11-16T14:00:00+00:00

A flaw was found in the Linux kernels memory deduplication mechanism. Previous work has shown that memory deduplication can be attacked via a local exploitation mechanism. The same technique can be used if an attacker can upload page sized files and detect the change in access time from a networked service to determine if the page has been merged.

Statement: This issue affects the versions of the Linux Kernel as shipped with Red Hat Enterprise Linux 6,7 and 8. Red Hat Product Security has rated this issue as having Moderate security impact. Additionally a workaround is available. A future update may address this issue. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.

Remediation:
The  mitigation shown below has a potentially significant impact on system performance and stability. It should be carefully tested prior to deployment:

- Deactivation of memory deduplication 

Deactivating memory deduplication will effectively mitigate all attack vectors. This measure unfortunately eliminates all the highly appreciated benefits of memory deduplication, namely the increase of operational cost-effectiveness through inter-VM memory sharing.  This will cause an increase in the amount of memory required and in some situations may adversely impact performance (e.g. due to slower swap space being used). It is recommended that customers test this workaround before using it in production.  See https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/virtualization_tuning_and_optimization_guide/sect-ksm-deactivating_ksm for how to disable KSM from Red Hat Enterprise Linux 6 and newer.

- Disabling services and firewall rules.

The attack uses the response time of services on the system.  By limiting access to services an attacker must connect to the service to successful carry out the exploit.  Reducing the number of systems that are allowed to connect to the service will prevent an attack from working when launched outside an allowed ranges.  While this does not prevent an attack from working, it will reduce the amount of systems that an attacker can launch an attack from.

Revert "Revert "block, bfq: honor already-setup queue merges""
CVE: CVE-2021-47646
Component: kernel
CWE: CWE-416
Severity: Moderate
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

Revert "Revert "block, bfq: honor already-setup queue merges""

A crash [1] happened to be triggered in conjunction with commit
2d52c58b9c9b ("block, bfq: honor already-setup queue merges"). The
latter was then reverted by commit ebc69e897e17 ("Revert "block, bfq:
honor already-setup queue merges""). Yet, the reverted commit was not
the one introducing the bug. In fact, it actually triggered a UAF
introduced by a different commit, and now fixed by commit d29bd41428cf
("block, bfq: reset last_bfqq_created on group change").

So, there is no point in keeping commit 2d52c58b9c9b ("block, bfq:
honor already-setup queue merges") out. This commit restores it.

udf: Fix NULL pointer dereference in udf_symlink function
CVE: CVE-2021-47353
Component: kernel
CWE: CWE-476
Severity: Moderate
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

A vulnerability was found in the Linux kernel's UDF file system driver, where the udf_symlink function can dereference a NULL pointer. This occurs because the function uses a value returned from udf_tgetblk without checking if it is NULL, potentially causing system crashes if sb_getblk fails.

Statement: This vulnerability is rated as a moderate severity because it can lead to system crashes due to a NULL pointer dereference, but it requires specific conditions related to file system operations.
