CVSS v3.1 |
| A flaw was found in Picketlink's SP signature validation; a SAML response containing zero assertion elements matching the signature check can allow an attacker to forge a SAML response and auth as any principal with any roles on the protected application. |
| A flaw was found in JBoss marshalling. The Infinispan session replication path deserializes replicated session data via the JBoss Marshalling River unmarshaller with no class filtering — enabling RCE via deserialization gadget chains on every cluster node. |
| the Undertow AJP listener honours forged ssl_cert and is_ssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP protocol. |
| A flaw was found in Picketlink Federation SAML; the unsolcited response handler would accept forged assertions with no verification or validation, permitting an unauthed attacker to authenticate as any principal in any role. This could lead to information disclosure, access to restricted operations, or other flaws. |
| This issue was addressed by enforcing library validation on the affected binaries. This issue is fixed in Xcode 27. An app may be able to break out of its sandbox. |
| A security flaw has been discovered in PostyBirb Plus up to 3.1.75. Affected by this vulnerability is an unknown functionality of the file ui/src/views/submissions/submission-forms/form-components/DescriptionInput.tsx of the component Submission Description Editor. The manipulation results in cross site scripting. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks. Upgrading to version 3.1.76 addresses this issue. The patch is identified as 6b11c2345ad98ae59fd5404a9f1024eb1d10c8a4. It is advisable to upgrade the affected component. |
| Uncontrolled Recursion vulnerability in Apache Thrift Java bindings.
This issue affects Apache Thrift: before 0.24.0.
Users are recommended to upgrade to version 0.24.0, which fixes the issue. |
| **UNSUPPORTED WHEN ASSIGNED**
JavaNativeMessageDecoder in the MINA 3.0 codec module calls ObjectInputStream.readObject() on frame bytes with no class filter, so an
application that puts it in front of an untrusted peer is open to gadget-chain RCE.
As the 3.0.0 branch is inactive, we do not plan to release a version that fixes this issue.
Users are recommended to use the latest Apache MINA 2.2.X branch. |
| Heap-based buffer overflow in Windows Win32K - GRFX allows an authorized attacker to elevate privileges locally. |
| Out-of-bounds read in Windows GDI allows an unauthorized attacker to disclose information over a network. |
| Out-of-bounds read in Windows Win32 Kernel Subsystem allows an authorized attacker to disclose information locally. |
| Use after free in Windows Win32 Kernel Subsystem allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Kernel allows an authorized attacker to elevate privileges locally. |
| ShowDoc 2.8.14 before 3.9.6 contains a code injection vulnerability in its Mock feature that allows authenticated users to execute shell commands through mockjs templates. Attackers can store a template via MockController::add with escaped parentheses that mockjs evaluates with eval(), then trigger it through MockController::infoByKey to run commands, as root in the official Docker image. |
| LearnHouse before 1.1.1 contains a missing authorization vulnerability in the assignment API that allows authenticated users to read other users' grades and submissions. Attackers can supply another user_id to the submissions grade endpoint or query submission read functions to view other students' work, grades and instructor feedback. |
| Unintended proxy or intermediary in Azure Arc allows an authorized attacker to elevate privileges over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: libiscsi: Validate the ITT reflected in a Reject PDU
A Reject PDU carries a copy of the header it rejects, and
iscsi_handle_reject() takes the ITT out of that copy to find the task to
clean up:
memcpy(&rejected_pdu, data, sizeof(struct iscsi_hdr));
...
task = iscsi_itt_to_task(conn, rejected_pdu.itt);
That value is whatever the target put there. iscsi_itt_to_task() bounds
the index against cmds_max and checks nothing else, so any task in the
pool can be named, and iscsi_nop_out_rsp() then completes it.
An index that has never been used gives a NULL task->conn: the pool is
zeroed at session setup and conn is assigned only when a task is
allocated. If the task was used and returned, iscsi_complete_task() hits
its WARN_ON_ONCE(task->state == ISCSI_TASK_FREE) and the refcount
underflows. An in-flight SCSI command is completed as successful - a 1
MiB read returned 1048576 with none of its buffer written and no
warning.
Validate the reflected ITT the way iscsi_itt_to_ctask() validates a
command ITT, and require the task to be in flight and not a SCSI
command.

| In the Linux kernel, the following vulnerability has been resolved:
spi: imx: fix slab corruption from undersized DMA bounce buffers
Since commit faa8e404ad8e ("spi: imx: support dynamic burst length for
ECSPI DMA mode"), the driver allocates its private DMA TX/RX buffers
with kzalloc(dma_len), where dma_len is only rounded up to 4 bytes, but
maps, syncs and unmaps them with DMA_CACHE_ALIGNED_LEN(dma_len), i.e.
rounded up to the cache line size. As a result, the DMA API operates on
memory beyond the end of the allocation.
This was observed on a custom i.MX8MP platform with an mcp251xfd CAN
controller under heavy RPMSG load, as a series of refcount_t warnings
triggered from rpmsg_recv_done() in virtio_rpmsg_bus:
refcount_t: addition on 0; use-after-free.
refcount_t: underflow; use-after-free.
refcount_t: saturated; leaking memory.
Leading finally to an "Unable to handle kernel paging request" oops.
Reproducing this problem took between 30 minutes and roughly 30 hours
under the same workload.
Hardware watchpoints on the refcount of a struct rpmsg_endpoint showed
it was overwritten from 2 to 1 by __pi_memcpy_generic() in the
irq/155-spi2.0 thread. Additionally it was found that a "normal"
rpmsg_recv_done() took 11µs +/-2µs from its kref_get to kref_put. In
the error case the same sequence took about 215µs +/-10µs. Based on
this, an LLM was used to identify the size mismatch fixed here.
Allocate the buffers with DMA_CACHE_ALIGNED_LEN(dma_len) so they cover
the full mapped length, and use the same length for
dma_sync_single_for_cpu() to stay consistent with map and unmap.
With this patch applied, the same workload ran for more than 200 hours
without the problem reproducing. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SEV: Fix page dirtying in sev_gmem_post_populate()
set_page_dirty() requires that the caller holds some kind of lock to
ensure that the page's mapping does not concurrently go away.
That is not the case for a random page we got from get_user_pages_fast(),
so use set_page_dirty_lock().

| In the Linux kernel, the following vulnerability has been resolved:
unicode: free the map after a grace period
generic_ci_d_hash() and generic_ci_d_compare() read sb->s_encoding and
dereference the unicode map while a pathwalk in rcu mode holds nothing
but rcu_read_lock(). The filesystems that use them, ext4, f2fs and
tmpfs, drop the map with utf8_unload() from ->put_super(), which runs
when the last reference to the mount goes away. A lookup that is still
inside such a filesystem at that point reads a freed map.
With a pathwalk held up in utf8_casefold_hash() while the last reference
to a casefolded tmpfs goes away:

cleanup_mnt+0x9f/0x130
So far that has been hard to hit. umount(2) waits for a grace period
in namespace_unlock() before it drops the mount, so only a mount whose
last reference goes away elsewhere, like the close of a file or a chdir
out of a lazily unmounted directory, can race a walker. So it is
reachable.
Delay the free until a grace period has passed. The map and the data
table it holds a reference to then outlive any pathwalk that found the
superblock before the mount went away. The reference on the data table
module is dropped from the rcu callback as well. utf8-core is built in
whenever CONFIG_UNICODE is set, so there is no module exit that would
have to wait for the callbacks.
Overlayfs points the s_encoding of an overlay at the map of its first
layer without taking a reference of its own. That stays correct. The
layer is held by the overlay, so its map is dropped only after the
overlay is gone. |
