CWE: CWE-125
Description: A flaw was found in stb_image. This issue occurs while processing the frame header information when the plane sampling configurations are calculated in two different ways, generating different results due to integer approximation. The value is further used to access several buffers, leading to a heap based out-of-bound read. This causes a heap data leak or an application crash, resulting in a denial of service.
Statement: Although the NVD CVSSv3.1 scoring point to a 8.1, Red Hat considers the impact to be Moderate as this flaw can not be used to perform arbitrary code execution, needs local access to be exploited, and the amount of leaked information is constrained to a few bytes within the process heap.

CWE: CWE-200
Description: For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory. For example a request to `/concat?/%2557EB-INF/web.xml` can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application.
Statement: In OpenShift Container Platform (OCP), the hive/presto/hadoop components that comprise the OCP metering stack, ship the vulnerable version of jetty.
Since the release of OCP 4.6, the metering product has been deprecated [1], hence the affected components are marked as wontfix.
This may be fixed in the future.

[1] https://docs.openshift.com/container-platform/4.6/release_notes/ocp-4-6-release-notes.html#ocp-4-6-metering-operator-deprecated

Red Hat OpenStack Platform's OpenDaylight will not be updated for this flaw because it was deprecated as of OpenStack Platform 14 and is only receiving security fixes for Important and Critical flaws.

Red Hat CodeReady Studio 12 is not affected by this flaw because it does not ship the vulnerable components (ConcatServlet or WelcomeFilter) of jetty.

Red Hat Enterprise Linux 8 is not affected by this flaw because it does not ship the vulnerable components (ConcatServlet or WelcomeFilter) of jetty.

Red Hat Enterprise Linux 7 ships the vulnerable component of jetty, but only in the optional repository and thus this flaw is out of support scope for Red Hat Enterprise Linux 7.

CVE-2021-47608 (Low severity, published 2024-06-18)
CVSS score: 4.4 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L)
CWE: CWE-200
Description: In the Linux kernel, the following vulnerability has been resolved:

bpf: Fix kernel address leakage in atomic fetch

The change in commit 37086bfdc737 ("bpf: Propagate stack bounds to registers
in atomics w/ BPF_FETCH") around check_mem_access() handling is buggy since
this would allow for unprivileged users to leak kernel pointers. For example,
an atomic fetch/and with -1 on a stack destination which holds a spilled
pointer will migrate the spilled register type into a scalar, which can then
be exported out of the program (since scalar != pointer) by dumping it into
a map value.

The original implementation of XADD was preventing this situation by using
a double call to check_mem_access() one with BPF_READ and a subsequent one
with BPF_WRITE, in both cases passing -1 as a placeholder value instead of
register as per XADD semantics since it didn't contain a value fetch. The
BPF_READ also included a check in check_stack_read_fixed_off() which rejects
the program if the stack slot is of __is_pointer_value() if dst_regno < 0.
The latter is to distinguish whether we're dealing with a regular stack spill/
fill or some arithmetical operation which is disallowed on non-scalars, see
also 6e7e63cbb023 ("bpf: Forbid XADD on spilled pointers for unprivileged
users") for more context on check_mem_access() and its handling of placeholder
value -1.

One minimally intrusive option to fix the leak is for the BPF_FETCH case to
initially check the BPF_READ case via check_mem_access() with -1 as register,
followed by the actual load case with non-negative load_reg to propagate
stack bounds to registers.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

scsi: core: Fix error handling of scsi_host_alloc()

After device is initialized via device_initialize(), or its name is set via

device name will be leaked because it is allocated dynamically in
dev_set_name().

Fix the leak by replacing kfree() with put_device(). Since
scsi_host_dev_release() properly handles IDA and kthread removal, remove
special-casing these from the error handling as well.
