| Parallels Desktop Updater Improper Initialization Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop. An attacker must first obtain the ability to execute low-privileged code on the target host system in order to exploit this vulnerability.
The specific flaw exists within the Updater service. The issue results from the lack of proper initialization of environment variables. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
. Was ZDI-CAN-18253. |
| vantage6-UI is the official user interface for the vantage6 server. In affected versions a number of security headers are not set. This issue has been addressed in commit `68dfa6614` which is expected to be included in future releases. Users are advised to upgrade when a new release is made. While an upgrade path is not available users may modify the docker image build to insert the headers into nginx.

| A Zigbee Radio Co-Processor (RCP), which is using SiLabs EmberZNet Zigbee stack, was unable to send messages to the host system (CPCd) due to heavy Zigbee traffic, resulting in a Denial of Service (DoS) attack, Only hard reset will bring the device to normal operation |
| In OceanBase's Oracle tenant mode, a malicious user with specific privileges can achieve privilege escalation to SYS-level access by executing carefully crafted commands.
This vulnerability only affects OceanBase tenants in Oracle mode. Tenants in MySQL mode are unaffected. |
| A race condition was addressed with improved locking. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave, watchOS 7.3, tvOS 14.4, iOS 14.4 and iPadOS 14.4. A malicious application may be able to elevate privileges. Apple is aware of a report that this issue may have been actively exploited.. |
| The attacker can use the raft server protocol in an unauthenticated way. The attacker can see the server's resources, including directories and files.
This issue affects Apache Zeppelin: from 0.10.1 up to 0.12.0.
Users are recommended to upgrade to version 0.12.0, which fixes the issue by removing the Cluster Interpreter. |
| A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP and SMB2_LOGOFF commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/lima: fix shared irq handling on driver remove
lima uses a shared interrupt, so the interrupt handlers must be prepared
to be called at any time. At driver removal time, the clocks are
disabled early and the interrupts stay registered until the very end of
the remove process due to the devm usage.
This is potentially a bug as the interrupts access device registers
which assumes clocks are enabled. A crash can be triggered by removing
the driver in a kernel with CONFIG_DEBUG_SHIRQ enabled.
This patch frees the interrupts at each lima device finishing callback
so that the handlers are already unregistered by the time we fully
disable clocks. |

scsi: qedf: Add stag_work to all the vports

| A CWE-668: Exposure of Resource to Wrong Sphere vulnerability exists that exposes TGML diagram resources
to the wrong control sphere, providing other authenticated users with potentially inappropriate access to TGML
diagrams. |
| WordPress 3.5 through 6.8.2 allows remote attackers to guess titles of private and draft posts via pingback.ping XML-RPC requests. NOTE: the Supplier is not changing this behavior. |
| A remote file disclosure vulnerability exists in EasyCafe Server 2.2.14, exploitable by unauthenticated remote attackers via TCP port 831. The server listens for a custom protocol where opcode 0x43 can be used to request arbitrary files by absolute path. If the file exists and is accessible, its content is returned without authentication. This flaw allows attackers to retrieve sensitive files such as system configuration, password files, or application data. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: don't skip expired elements during walk
There is an asymmetry between commit/abort and preparation phase if the
following conditions are met:
1. set is a verdict map ("1.2.3.4 : jump foo")
2. timeouts are enabled
In this case, following sequence is problematic:
1. element E in set S refers to chain C
2. userspace requests removal of set S
3. kernel does a set walk to decrement chain->use count for all elements
from preparation phase
4. kernel does another set walk to remove elements from the commit phase
(or another walk to do a chain->use increment for all elements from
abort phase)
If E has already expired in 1), it will be ignored during list walk, so its use count
won't have been changed.
Then, when set is culled, ->destroy callback will zap the element via
nf_tables_set_elem_destroy(), but this function is only safe for
elements that have been deactivated earlier from the preparation phase:
lack of earlier deactivate removes the element but leaks the chain use
count, which results in a WARN splat when the chain gets removed later,
plus a leak of the nft_chain structure.
Update pipapo_get() not to skip expired elements, otherwise flush
command reports bogus ENOENT errors. |
| DIRAC is an interware, meaning a software framework for distributed computing. Prior to version 8.0.41, during the proxy generation process (e.g., when using `dirac-proxy-init`), it is possible for unauthorized users on the same machine to gain read access to the proxy. This allows the user to then perform any action that is possible with the original proxy. This vulnerability only exists for a short period of time (sub-millsecond) during the generation process. Version 8.0.41 contains a patch for the issue. As a workaround, setting the `X509_USER_PROXY` environment variable to a path that is inside a directory that is only readable to the current user avoids the potential risk. After the file has been written, it can be safely copied to the standard location (`/tmp/x509up_uNNNN`). |
| In the Linux kernel, the following vulnerability has been resolved:
efi: libstub: only free priv.runtime_map when allocated
priv.runtime_map is only allocated when efi_novamap is not set.
Otherwise, it is an uninitialized value. In the error path, it is freed
unconditionally. Avoid passing an uninitialized value to free_pool.
Free priv.runtime_map only when it was allocated.
This bug was discovered and resolved using Coverity Static Analysis

| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: add srng->lock for ath11k_hal_srng_* in monitor mode
ath11k_hal_srng_* should be used with srng->lock to protect srng data.
For ath11k_dp_rx_mon_dest_process() and ath11k_dp_full_mon_process_rx(),
they use ath11k_hal_srng_* for many times but never call srng->lock.
So when running (full) monitor mode, warning will occur:
RIP: 0010:ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k]
Call Trace:
? ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k]

__napi_poll+0x30/0x1f0
net_rx_action+0x198/0x320
__do_softirq+0xdd/0x319
So add srng->lock for them to avoid such warnings.
Inorder to fetch the srng->lock, should change srng's definition from
'void' to 'struct hal_srng'. And initialize them elsewhere to prevent
one line of code from being too long. This is consistent with other ring
process functions, such as ath11k_dp_process_rx().

net/smc: initialize close_work early to avoid warning
We encountered a warning that close_work was canceled before
initialization.
WARNING: CPU: 7 PID: 111103 at kernel/workqueue.c:3047 __flush_work+0x19e/0x1b0
Workqueue: events smc_lgr_terminate_work [smc]

ret_from_fork+0x22/0x30
This is because when smc_close_cancel_work is triggered, e.g. the RDMA
driver is rmmod and the LGR is terminated, the conn->close_work is
flushed before initialization, resulting in WARN_ON(!work->func).
__smc_lgr_terminate | smc_connect_{rdma|ism}

\- cancel_work_sync |
\- __flush_work |

So fix this by initializing close_work before establishing the

nfsd: fix legacy client tracking initialization
Get rid of the nfsd4_legacy_tracking_ops->init() call in
check_for_legacy_methods(). That will be handled in the caller
(nfsd4_client_tracking_init()). Otherwise, we'll wind up calling
nfsd4_legacy_tracking_ops->init() twice, and the second time we'll
trigger the BUG_ON() in nfsd4_init_recdir(). |
