CVSS v3.1 |
| A buffer overflow was found in Shim in the 32-bit system. The overflow happens due to an addition operation involving a user-controlled value parsed from the PE binary being used by Shim. This value is further used for memory allocation operations, leading to a heap-based buffer overflow. This flaw causes memory corruption and can lead to a crash or data integrity issues during the boot phase. |
| A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a crash under certain circumstances. |
| A flaw was found in Red Hat's AMQ Broker, which stores certain passwords in a secret security-properties-prop-module, defined in ActivemqArtemisSecurity CR; however, they are shown in plaintext in the StatefulSet details yaml of AMQ Broker. |
| An HTML injection flaw was found in Controller in the user interface settings. This flaw allows an attacker to capture credentials by creating a custom login page by injecting HTML, resulting in a complete compromise. |
| A logic flaw exists in Ansible Automation platform. Whenever a private project is created with incorrect credentials, they are logged in plaintext. This flaw allows an attacker to retrieve the credentials from the log, resulting in the loss of confidentiality, integrity, and availability. |
| A vulnerability was found in aap-gateway. A Cross-site Scripting (XSS) vulnerability exists in the gateway component. This flaw allows a malicious user to perform actions that impact users by using the "?next=" in a URL, which can lead to redirecting, injecting malicious script, stealing sessions and data. |
| A regression was introduced in the Red Hat build of python-eventlet due to a change in the patch application strategy, resulting in a patch for CVE-2021-21419 not being applied for all builds of all products. |
| A flaw was found in CRI-O that involves an experimental annotation leading to a container being unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes scheduler and potentially resulting in a denial of service in the node. |
| A vulnerability was found in Perl. This security issue occurs while Perl for Windows relies on the system path environment variable to find the shell (`cmd.exe`). When running an executable that uses the Windows Perl interpreter, Perl attempts to find and execute `cmd.exe` within the operating system. However, due to path search order issues, Perl initially looks for cmd.exe in the current working directory. This flaw allows an attacker with limited privileges to place`cmd.exe` in locations with weak permissions, such as `C:\ProgramData`. By doing so, arbitrary code can be executed when an administrator attempts to use this executable from these compromised locations. |
| A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database. |
| A flaw was found in Keylime. Due to their blocking nature, the Keylime registrar is subject to a remote denial of service against its SSL connections. This flaw allows an attacker to exhaust all available connections. |
| An absolute path traversal attack exists in the Ansible automation platform. This flaw allows an attacker to craft a malicious Ansible role and make the victim execute the role. A symlink can be used to overwrite a file outside of the extraction path. |
| A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully. |
| A flaw was found in the Skupper operator, which may permit a certain configuration to create a service account that would allow an authenticated attacker in the adjacent cluster to view deployments in all namespaces in the cluster. This issue permits unauthorized viewing of information outside of the user's purview. |
| In the Linux kernel, the following vulnerability has been resolved:
sched/core: Do not requeue task on CPU excluded from cpus_mask
The following warning was triggered on a large machine early in boot on
a distribution kernel but the same problem should also affect mainline.
WARNING: CPU: 439 PID: 10 at ../kernel/workqueue.c:2231 process_one_work+0x4d/0x440
Call Trace:

</TASK>
Commit c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
optimises ttwu by queueing a task that is descheduling on the wakelist,
but does not check if the task descheduling is still allowed to run on that CPU.
In this warning, the problematic task is a workqueue rescue thread which
checks if the rescue is for a per-cpu workqueue and running on the wrong CPU.
While this is early in boot and it should be possible to create workers,
the rescue thread may still used if the MAYDAY_INITIAL_TIMEOUT is reached
or MAYDAY_INTERVAL and on a sufficiently large machine, the rescue
thread is being used frequently.
Tracing confirmed that the task should have migrated properly using the
stopper thread to handle the migration. However, a parallel wakeup from udev
running on another CPU that does not share CPU cache observes p->on_cpu and
uses task_cpu(p), queues the task on the old CPU and triggers the warning.
Check that the wakee task that is descheduling is still allowed to run
on its current CPU and if not, wait for the descheduling to complete
and select an allowed CPU. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: do not allow CHAIN_ID to refer to another table
When doing lookups for chains on the same batch by using its ID, a chain
from a different table can be used. If a rule is added to a table but
refers to a chain in a different table, it will be linked to the chain in
table2, but would have expressions referring to objects in table1.
Then, when table1 is removed, the rule will not be removed as its linked to
a chain in table2. When expressions in the rule are processed or removed,
that will lead to a use-after-free.
When looking for chains by ID, use the table that was used for the lookup
by name, and only return chains belonging to that same table. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: Fix simplification of devm_spi_register_controller
This reverts commit 59ebbe40fb51 ("spi: simplify
devm_spi_register_controller").
If devm_add_action() fails in devm_add_action_or_reset(),
devm_spi_unregister() will be called, it decreases the
refcount of 'ctlr->dev' to 0, then it will cause uaf in
the drivers that calling spi_put_controller() in error path. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc3-topology: Prevent double freeing of ipc_control_data via load_bytes
We have sanity checks for byte controls and if any of the fail the locally
allocated scontrol->ipc_control_data is freed up, but not set to NULL.
On a rollback path of the error the higher level code will also try to free
the scontrol->ipc_control_data which will eventually going to lead to
memory corruption as double freeing memory is not a good thing. |
| In the Linux kernel, the following vulnerability has been resolved:
vfio: Split migration ops from main device ops
vfio core checks whether the driver sets some migration op (e.g.
set_state/get_state) and accordingly calls its op.
However, currently mlx5 driver sets the above ops without regards to its
migration caps.
This might lead to unexpected usage/Oops if user space may call to the
above ops even if the driver doesn't support migration. As for example,
the migration state_mutex is not initialized in that case.
The cleanest way to manage that seems to split the migration ops from
the main device ops, this will let the driver setting them separately
from the main ops when it's applicable.
As part of that, validate ops construction on registration and include a
check for VFIO_MIGRATION_STOP_COPY since the uAPI claims it must be set
in migration_flags.
HISI driver was changed as well to match this scheme.
This scheme may enable down the road to come with some extra group of
ops (e.g. DMA log) that can be set without regards to the other options
based on driver caps. |
| A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161. This vulnerability occurs due to a dangling pointer in the Primetime SDK related to media player handling of listener objects. A successful attack can lead to arbitrary code execution. This was exploited in the wild in January and February 2018. |
