CVSS v3.1 |
| The Team Section Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's block in all versions up to, and including, 2.0.0 due to insufficient input sanitization and output escaping on user-supplied social network link URLs. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
| The Homey theme for WordPress is vulnerable to privilege escalation in all versions up to, and including, 2.4.2. This is due to the plugin allowing users who are registering new accounts to set their own role. This makes it possible for unauthenticated attackers to gain elevated privileges by creating an account with the Administrator, Editor, or Shop Manager role. |
| In the Linux kernel, the following vulnerability has been resolved:
mm: swap: check for stable address space before operating on the VMA
It is possible to hit a zero entry while traversing the vmas in unuse_mm()
called from swapoff path and accessing it causes the OOPS:
Unable to handle kernel NULL pointer dereference at virtual address
0000000000000446--> Loading the memory from offset 0x40 on the
XA_ZERO_ENTRY as address.
Mem abort info:
ESR = 0x0000000096000005
EC = 0x25: DABT (current EL), IL = 32 bits
SET = 0, FnV = 0
EA = 0, S1PTW = 0
FSC = 0x05: level 1 translation fault
The issue is manifested from the below race between the fork() on a
process and swapoff:
fork(dup_mmap()) swapoff(unuse_mm)
--------------- -----------------
1) Identical mtree is built using
__mt_dup().
2) copy_pte_range()-->
copy_nonpresent_pte():
The dst mm is added into the
mmlist to be visible to the
swapoff operation.
3) Fatal signal is sent to the parent
process(which is the current during the
fork) thus skip the duplication of the
vmas and mark the vma range with
XA_ZERO_ENTRY as a marker for this process
that helps during exit_mmap().
4) swapoff is tried on the
'mm' added to the 'mmlist' as
part of the 2.
5) unuse_mm(), that iterates
through the vma's of this 'mm'
will hit the non-NULL zero entry
and operating on this zero entry
as a vma is resulting into the
oops.
The proper fix would be around not exposing this partially-valid tree to
others when droping the mmap lock, which is being solved with [1]. A
simpler solution would be checking for MMF_UNSTABLE, as it is set if
mm_struct is not fully initialized in dup_mmap().
Thanks to Liam/Lorenzo/David for all the suggestions in fixing this
issue. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix folio is still mapped when deleted
Migration may be raced with fallocating hole. remove_inode_single_folio
will unmap the folio if the folio is still mapped. However, it's called
without folio lock. If the folio is migrated and the mapped pte has been
converted to migration entry, folio_mapped() returns false, and won't
unmap it. Due to extra refcount held by remove_inode_single_folio,
migration fails, restores migration entry to normal pte, and the folio is
mapped again. As a result, we triggered BUG in filemap_unaccount_folio.
The log is as follows:

| A flaw has been found in Flycatcher Toys smART Sketcher up to 2.0. This affects an unknown part of the component Bluetooth Low Energy Interface. This manipulation causes missing authentication. The attack can only be done within the local network. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way. |
| In the Linux kernel, the following vulnerability has been resolved:
Squashfs: fix uninit-value in squashfs_get_parent
Syzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug.
This is caused by open_by_handle_at() being called with a file handle
containing an invalid parent inode number. In particular the inode number
is that of a symbolic link, rather than a directory.
Squashfs_get_parent() gets called with that symbolic link inode, and
accesses the parent member field.
unsigned int parent_ino = squashfs_i(inode)->parent;
Because non-directory inodes in Squashfs do not have a parent value, this
is uninitialised, and this causes an uninitialised value access.
The fix is to initialise parent with the invalid inode 0, which will cause
an EINVAL error to be returned.
Regular inodes used to share the parent field with the block_list_start
field. This is removed in this commit to enable the parent field to
contain the invalid inode number 0. |

Such manipulation of the argument latitude leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product is distributed under multiple different names. The vendor was contacted early about this disclosure but did not respond in any way. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_acm: Refactor bind path to use __free()
After an bind/unbind cycle, the acm->notify_req is left stale. If a
subsequent bind fails, the unified error label attempts to free this
stale request, leading to a NULL pointer dereference when accessing
ep->ops->free_request.
Refactor the error handling in the bind path to use the __free()
automatic cleanup mechanism.

| In the Linux kernel, the following vulnerability has been resolved:
net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast
syzbot reported WARNING in rtl8150_start_xmit/usb_submit_urb.
This is the sequence of events that leads to the warning:
rtl8150_start_xmit() {
netif_stop_queue();
usb_submit_urb(dev->tx_urb);
}
rtl8150_set_multicast() {
netif_stop_queue();
netif_wake_queue(); <-- wakes up TX queue before URB is done
}
rtl8150_start_xmit() {
netif_stop_queue();
usb_submit_urb(dev->tx_urb); <-- double submission
}
rtl8150_set_multicast being the ndo_set_rx_mode callback should not be
calling netif_stop_queue and notif_start_queue as these handle
TX queue synchronization.
The net core function dev_set_rx_mode handles the synchronization
for rtl8150_set_multicast making it safe to remove these locks. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/vaddr: do not repeat pte_offset_map_lock() until success
DAMON's virtual address space operation set implementation (vaddr) calls
pte_offset_map_lock() inside the page table walk callback function. This
is for reading and writing page table accessed bits. If
pte_offset_map_lock() fails, it retries by returning the page table walk
callback function with ACTION_AGAIN.
pte_offset_map_lock() can continuously fail if the target is a pmd
migration entry, though. Hence it could cause an infinite page table walk
if the migration cannot be done until the page table walk is finished.
This indeed caused a soft lockup when CPU hotplugging and DAMON were
running in parallel.
Avoid the infinite loop by simply not retrying the page table walk. DAMON
is promising only a best-effort accuracy, so missing access to such pages
is no problem. |

| In the Linux kernel, the following vulnerability has been resolved:
fs/notify: call exportfs_encode_fid with s_umount
Calling intotify_show_fdinfo() on fd watching an overlayfs inode, while
the overlayfs is being unmounted, can lead to dereferencing NULL ptr.

| A `named` caching resolver that is configured to send ECS (EDNS Client Subnet) options may be vulnerable to a cache-poisoning attack.
This issue affects BIND 9 versions 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.37-S1, and 9.20.9-S1 through 9.20.10-S1. |
| Certain DVR/NVR models developed by Merit LILIN has a OS Command Injection vulnerability, allowing authenticated remote attackers to inject arbitrary OS commands and execute them on the device. |
| The SimpleShop plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.10.0. This is due to missing or incorrect nonce validation on the maybe_disconnect_simpleshop function. This makes it possible for unauthenticated attackers to disconnect the site from simpleshop via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-net: fix received length check in big packets
Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
for big packets"), when guest gso is off, the allocated size for big
packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
negotiated MTU. The number of allocated frags for big packets is stored
in vi->big_packets_num_skbfrags.
Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect
length), we need a check in virtio_net receive path. Currently, the
check is not adapted to the new change which can lead to NULL page
pointer dereference in the below while loop when receiving length that
is larger than the allocated one.
This commit fixes the received length check corresponding to the new
change. |
| Certain IP Camera models developed by Merit LILIN has a OS Command Injection vulnerability, allowing authenticated remote attackers to inject arbitrary OS commands and execute them on the device. |
| The Save as PDF Plugin by PDFCrowd plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘options’ parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. NOTE: Successful exploitation of this vulnerability requires that the PDFCrowd API key is blank (also known as "demo mode", which is the default configuration when the plugin is installed) or known. |
| In the Linux kernel, the following vulnerability has been resolved:
s390: Disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP
As reported by Luiz Capitulino enabling HVO on s390 leads to reproducible
crashes. The problem is that kernel page tables are modified without
flushing corresponding TLB entries.
Even if it looks like the empty flush_tlb_all() implementation on s390 is
the problem, it is actually a different problem: on s390 it is not allowed
to replace an active/valid page table entry with another valid page table
entry without the detour over an invalid entry. A direct replacement may
lead to random crashes and/or data corruption.
In order to invalidate an entry special instructions have to be used
(e.g. ipte or idte). Alternatively there are also special instructions
available which allow to replace a valid entry with a different valid
entry (e.g. crdte or cspg).
Given that the HVO code currently does not provide the hooks to allow for
an implementation which is compliant with the s390 architecture
requirements, disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP again, which is
basically a revert of the original patch which enabled it. |
| The Essential Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's ew-author, ew-archive, ew-category, ew-page, and ew-menu shortcodes in all versions up to, and including, 3.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This vulnerability was partially fixed in version 3.0. |
