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

net/mlx5e: CT, Fix multiple allocations and memleak of mod acts

CT clear action offload adds additional mod hdr actions to the
flow's original mod actions in order to clear the registers which
hold ct_state.
When such flow also includes encap action, a neigh update event
can cause the driver to unoffload the flow and then reoffload it.

Each time this happens, the ct clear handling adds that same set
of mod hdr actions to reset ct_state until the max of mod hdr
actions is reached.

Also the driver never releases the allocated mod hdr actions and
causing a memleak.

Fix above two issues by moving CT clear mod acts allocation
into the parsing actions phase and only use it when offloading the rule.
The release of mod acts will be done in the normal flow_put().

CWE: CWE-287
Description: A timing attack was found in the mailman administrative REST API due to the usage of a simple string comparison function when checking the password. This flaw allows an attacker who can talk to the REST API to discover the admin password due to timing leaks.
Statement: This issue did not affect the versions of mailman as shipped with Red Hat Enterprise Linux 6, 7, and 8 as they did not include support for the administrative REST API, which was introduced in mailman 3.

This flaw has a moderate Impact due to the requirement that is needed in order for an attacker to access the REST API. By default, the REST API is only accessible to localhost and it should never be exposed to the public internet, according to mailman documentation.

net: rds: fix memory leak in rds_recvmsg

Syzbot reported memory leak in rds. The problem
was in unputted refcount in case of error.

int rds_recvmsg(struct socket *sock, struct msghdr *msg, size_t size,
		int msg_flags)
{
...

	if (!rds_next_incoming(rs, &inc)) {

	if (rds_cmsg_recv(inc, msg, rs)) {
		ret = -EFAULT;
		goto out;
	}
...
out:
	return ret;
}

in case of rds_cmsg_recv() fail the refcount won't be
decremented. And it's easy to see from ftrace log, that
rds_inc_addref() don't have rds_inc_put() pair in
rds_recvmsg() after rds_cmsg_recv()

This was caused by PF queue pile fragmentation due to
flow director VSI queue being placed right after main VSI.
Because of this main VSI was not able to resize its
queue allocation for XDP resulting in no queues allocated
for main VSI when XDP was turned on.

Fix this by always allocating last queue in PF queue pile
for a flow director VSI.

CVSS score: 4.8 (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N)
CWE: CWE-79
Description: RabbitMQ is a multi-protocol messaging broker. In rabbitmq-server prior to version 3.8.18, when a federation link was displayed in the RabbitMQ management UI via the `rabbitmq_federation_management` plugin, its consumer tag was rendered without proper <script> tag sanitization. This potentially allows for JavaScript code execution in the context of the page. The user must be signed in and have elevated permissions (manage federation upstreams and policies) for this to occur. The vulnerability is patched in RabbitMQ 3.8.18. As a workaround, disable the `rabbitmq_federation_management` plugin and use [CLI tools](https://www.rabbitmq.com/cli.html) instead.
Statement: Red Hat OpenStack Platform ships a vulnerable version of RabbitMQ but it is not exposed outside the management network. As this network is tightly-regulated to OpenStack administrators, the risk for abuse is significantly reduced.

In addition, we now don't need to enable the clock from the

CVE-2021-39293 (Moderate severity, published 2021-08-17)
CVSS score: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-400
Description: A vulnerability was found in archive/zip of the Go standard library. Applications written in Go can panic or potentially exhaust system memory when parsing malformed ZIP files. An attacker capable of submitting a crafted ZIP file to a Go application using archive/zip to process that file could cause a denial of service via memory exhaustion or panic. This particular flaw is an incomplete fix for a previous flaw.
Statement: * In OpenShift Container Platform, multiple components are written in Go and use archive/zip from the standard library. However, all such components are short lived client side tools, not long lived server side executables. As the maximum impact of this vulnerability is a denial of service in client utilities, this vulnerability is rated Low for OpenShift Container Platform.

* This flaw is out of support scope for Red Hat Enterprise Linux 7. For more information about Red Hat Enterprise Linux support scope, please see https://access.redhat.com/support/policy/updates/errata

* Because Service Telemetry Framework1.2 will be retiring soon and the flaw's impact is lower, no update will be provided at this time for STF1.2's smart-gateway-container and sg-core-container.

Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-400: Uncontrolled Resource Consumption vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.

Red Hat restricts access to all platform information by default, granting access only after successful hard token-based multi-factor authentication (MFA) and enforcing least privilege to ensure only authorized roles can execute or modify code. The environment employs malicious code protections, including IDS/IPS and antimalware tools to detect threats and monitor resource usage, helping prevent uncontrolled consumption that could lead to system failure. Additional safeguards, such as web application firewalls and load-balancing strategies, protect against resource exhaustion and performance degradation. Event logs are centrally collected, correlated, and analyzed to support monitoring, alerting, and retention, aiding in the detection of abnormal behavior and potential denial-of-service (DoS) conditions. Static code analysis and peer reviews enforce strong input validation and error handling, reducing the likelihood of input-based DoS attacks.
CVE-2021-20266 (Low severity, published 2021-03-11)
CVSS score: 3.1 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L)
CWE: CWE-125
Description: A flaw was found in RPM’s hdrblobInit() in lib/header.c. This flaw allows an attacker who can modify the rpmdb to cause an out-of-bounds read. The highest threat from this vulnerability is to system availability.
Statement: In order to exploit this flaw with rpm tooling as shipped in Red Hat Enterprise Linux, an attacker would need to already have root access to modify the rpm database.
Mitigation: If using the headerCheck() and headerImport() APIs in your software, do not run them on headers from untrusted sources.
CVE-2021-38206 (Moderate severity, published 2021-05-30)
CVSS score: 6.5 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-476
Description: A flaw was found on the Linux kernel.  A NULL pointer dereference in the radiotap parser, leading to a denial of service, can occur in the mac80211 subsystem when a device supports only 5 GHz is used and frames with 802.11a rates are injected. The highest threat from this vulnerability is to system availability.
Statement: This issue only affects the Linux kernel versions as shipped with Red Hat Enterprise Linux 8.4 GA onwards. Previous Red Hat Enterprise Linux 8 kernel versions were not affected.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
CVE-2021-20289 (Low severity, published 2021-03-02)
CVSS score: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CWE: CWE-209
Description: A flaw was found in RESTEasy in all versions of RESTEasy up to 4.6.0.Final. The endpoint class and method names are returned as part of the exception response when RESTEasy cannot convert one of the request URI path or query values to the matching JAX-RS resource method's parameter value. The highest threat from this vulnerability is to data confidentiality.
CVE-2021-31162 (Moderate severity, published 2021-03-27)
CVSS score: 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-416
Description: In the standard library in Rust before 1.52.0, a double free can occur in the Vec::from_iter function if freeing the element panics.
