| BlueZ HID over GATT Profile Improper Access Control Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the implementation of the HID over GATT Profile. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-25177. |
| There is a LOW severity vulnerability affecting CPython, specifically the
'http.cookies' standard library module.
When parsing cookies that contained backslashes for quoted characters in
the cookie value, the parser would use an algorithm with quadratic
complexity, resulting in excess CPU resources being used while parsing the
value. |
| libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an
ASN.1 Generalized Time field. If given an syntactically incorrect field, the
parser might end up using -1 for the length of the *time fraction*, leading to
a `strlen()` getting performed on a pointer to a heap buffer area that is not
(purposely) null terminated.
This flaw most likely leads to a crash, but can also lead to heap contents
getting returned to the application when
[CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used. |
| A vulnerability was found in FFmpeg up to 7.0.1. It has been classified as critical. This affects the function pnm_decode_frame in the library /libavcodec/pnmdec.c. The manipulation leads to heap-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 7.0.2 is able to address this issue. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-273651. |
| When almost out-of-memory an elliptic curve key which was never allocated could have been freed again. This vulnerability affects Firefox < 128 and Thunderbird < 128. |
| A mismatch between allocator and deallocator could have led to memory corruption. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128. |
| There is a MEDIUM severity vulnerability affecting CPython.
Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar archives. |
| In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error, filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of URLs the function will result in invalid user information (username + password part of URLs) being treated as valid user information. This may lead to the downstream code accepting invalid URLs as valid and parsing them incorrectly. |
| Improper check of password character lenght in ORing IAP-420 allows a forced deadlock. This issue affects IAP-420: through 2.01e. |
| SNMP objects in NET-SNMP used in ORing IAP-420 allows Command Injection. This issue affects IAP-420: through 2.01e. |
| Missing input validation in the ORing IAP-420 web-interface allows stored Cross-Site Scripting (XSS).This issue affects IAP-420 version 2.01e and below. |
| Missing input validation in the ORing IAP-420 web-interface allows Cross-Site Scripting (XSS).This issue affects IAP-420 version 2.01e and below. |
| Missing input validation in the ORing IAP-420 web-interface allows authenticated Command Injections on OS level.This issue affects IAP-420 version 2.01e and below. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: Align BR/EDR JUST_WORKS paring with LE
This aligned BR/EDR JUST_WORKS method with LE which since 92516cd97fd4
("Bluetooth: Always request for user confirmation for Just Works")
always request user confirmation with confirm_hint set since the
likes of bluetoothd have dedicated policy around JUST_WORKS method
(e.g. main.conf:JustWorksRepairing).
CVE: CVE-2024-8805 |
| In the Linux kernel, the following vulnerability has been resolved:
netlink: terminate outstanding dump on socket close
Netlink supports iterative dumping of data. It provides the families
the following ops:
- start - (optional) kicks off the dumping process
- dump - actual dump helper, keeps getting called until it returns 0
- done - (optional) pairs with .start, can be used for cleanup
The whole process is asynchronous and the repeated calls to .dump
don't actually happen in a tight loop, but rather are triggered
in response to recvmsg() on the socket.
This gives the user full control over the dump, but also means that
the user can close the socket without getting to the end of the dump.
To make sure .start is always paired with .done we check if there
is an ongoing dump before freeing the socket, and if so call .done.
The complication is that sockets can get freed from BH and .done
is allowed to sleep. So we use a workqueue to defer the call, when
needed.
Unfortunately this does not work correctly. What we defer is not
the cleanup but rather releasing a reference on the socket.
We have no guarantee that we own the last reference, if someone
else holds the socket they may release it in BH and we're back
to square one.
The whole dance, however, appears to be unnecessary. Only the user
can interact with dumps, so we can clean up when socket is closed.
And close always happens in process context. Some async code may
still access the socket after close, queue notification skbs to it etc.
but no dumps can start, end or otherwise make progress.
Delete the workqueue and flush the dump state directly from the release
handler. Note that further cleanup is possible in -next, for instance
we now always call .done before releasing the main module reference,
so dump doesn't have to take a reference of its own. |

net/mlx5e: kTLS, Fix incorrect page refcounting
The kTLS tx handling code is using a mix of get_page() and
page_ref_inc() APIs to increment the page reference. But on the release
path (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.
This is an issue when using pages from large folios: the get_page()
references are stored on the folio page while the page_ref_inc()
references are stored directly in the given page. On release the folio
page will be dereferenced too many times.
This was found while doing kTLS testing with sendfile() + ZC when the
served file was read from NFS on a kernel with NFS large folios support
(commit 49b29a573da8 ("nfs: add support for large folios")). |
| In the Linux kernel, the following vulnerability has been resolved:
mm: revert "mm: shmem: fix data-race in shmem_getattr()"
Revert d949d1d14fa2 ("mm: shmem: fix data-race in shmem_getattr()") as
suggested by Chuck [1]. It is causing deadlocks when accessing tmpfs over
NFS.
As Hugh commented, "added just to silence a syzbot sanitizer splat: added
where there has never been any practical problem". |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: VMX: Bury Intel PT virtualization (guest/host mode) behind CONFIG_BROKEN
Hide KVM's pt_mode module param behind CONFIG_BROKEN, i.e. disable support
for virtualizing Intel PT via guest/host mode unless BROKEN=y. There are
myriad bugs in the implementation, some of which are fatal to the guest,
and others which put the stability and health of the host at risk.
For guest fatalities, the most glaring issue is that KVM fails to ensure
tracing is disabled, and *stays* disabled prior to VM-Enter, which is
necessary as hardware disallows loading (the guest's) RTIT_CTL if tracing
is enabled (enforced via a VMX consistency check). Per the SDM:
If the logical processor is operating with Intel PT enabled (if
IA32_RTIT_CTL.TraceEn = 1) at the time of VM entry, the "load
IA32_RTIT_CTL" VM-entry control must be 0.
On the host side, KVM doesn't validate the guest CPUID configuration
provided by userspace, and even worse, uses the guest configuration to
decide what MSRs to save/load at VM-Enter and VM-Exit. E.g. configuring
guest CPUID to enumerate more address ranges than are supported in hardware
will result in KVM trying to passthrough, save, and load non-existent MSRs,
which generates a variety of WARNs, ToPA ERRORs in the host, a potential
deadlock, etc. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix null-ptr-deref in block_touch_buffer tracepoint
Patch series "nilfs2: fix null-ptr-deref bugs on block tracepoints".
This series fixes null pointer dereference bugs that occur when using
nilfs2 and two block-related tracepoints.
This patch (of 2):
It has been reported that when using "block:block_touch_buffer"
tracepoint, touch_buffer() called from __nilfs_get_folio_block() causes a
NULL pointer dereference, or a general protection fault when KASAN is
enabled.
This happens because since the tracepoint was added in touch_buffer(), it
references the dev_t member bh->b_bdev->bd_dev regardless of whether the
buffer head has a pointer to a block_device structure. In the current
implementation, the block_device structure is set after the function
returns to the caller.
Here, touch_buffer() is used to mark the folio/page that owns the buffer
head as accessed, but the common search helper for folio/page used by the
caller function was optimized to mark the folio/page as accessed when it
was reimplemented a long time ago, eliminating the need to call
touch_buffer() here in the first place.
So this solves the issue by eliminating the touch_buffer() call itself. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix null-ptr-deref in block_dirty_buffer tracepoint
When using the "block:block_dirty_buffer" tracepoint, mark_buffer_dirty()
may cause a NULL pointer dereference, or a general protection fault when
KASAN is enabled.
This happens because, since the tracepoint was added in
mark_buffer_dirty(), it references the dev_t member bh->b_bdev->bd_dev
regardless of whether the buffer head has a pointer to a block_device
structure.
In the current implementation, nilfs_grab_buffer(), which grabs a buffer
to read (or create) a block of metadata, including b-tree node blocks,
does not set the block device, but instead does so only if the buffer is
not in the "uptodate" state for each of its caller block reading
functions. However, if the uptodate flag is set on a folio/page, and the
buffer heads are detached from it by try_to_free_buffers(), and new buffer
heads are then attached by create_empty_buffers(), the uptodate flag may
be restored to each buffer without the block device being set to
bh->b_bdev, and mark_buffer_dirty() may be called later in that state,
resulting in the bug mentioned above.
Fix this issue by making nilfs_grab_buffer() always set the block device
of the super block structure to the buffer head, regardless of the state
of the buffer's uptodate flag. |
