CVSS v3.1 |
| The Link Library WordPress plugin before 7.9.6 does not sanitize a user-supplied destination folder before writing a generated image to disk, allowing users with the Contributor role and above to create directories and write or overwrite image files anywhere the web server can write, including outside the site's document root.
The written file name is always numeric with a fixed image extension, so executable code cannot be planted this way. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/qaic: Address potential out-of-bounds read in resp_worker()
Although 'commit 2feec5ae5df7 ("accel/qaic: Handle DBC deactivation if the
owner went away")' fixes the scenario it was intended for by walking the
message and only decoding QAIC_TRANS_DEACTIVATE_FROM_DEV, if present, it
skipped over the bounds checking code that is included in decode_message().
This could lead to issues such as reading past the slab allocation's end,
infinite loops or kernel panics. For those issues to happen, a malformed
wire message is needed to be sent from the device.
Instead of duplicating the bounds checking code already present in
decode_message(), use the function inside resp_worker(). |
| AnyIO is a high level asynchronous concurrency and networking framework that works on top of either Trio or asyncio. In 4.14.0, AnyIO accepts the POSIX extra_groups argument in anyio.run_process() and anyio.open_process(), but open_process() forwards the group argument to the backend instead of extra_groups. A caller that supplies extra_groups=[] to clear inherited supplementary groups can therefore launch a child that retains the parent process groups, undermining a privilege-dropping boundary. If group is also supplied, the integer group value is passed where an iterable of supplementary groups is expected and the launch can fail with TypeError. This issue affects POSIX applications that rely on AnyIO subprocess helpers to launch less-privileged child processes. This issue is fixed in version 4.14.2. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Installer allows an authorized attacker to elevate privileges locally. |
| Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in IdeaSoft Software Industry and Trade Inc. Smart E-Commerce allows Reflected XSS.
This issue affects Smart E-Commerce: before 8.4.2.0. |

| In the Linux kernel, the following vulnerability has been resolved:
tracing: Don't dereference trace_event_file in deferred trigger free
The enable_event trigger defers trace_event_put_ref() to the
trigger free kthread, but the trace_event_file can already be freed
when the instance is removed.
Keep the trace_event_call directly in enable_trigger_data so the
deferred free does not access the freed trace_event_file. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Set the trace clock before registering the histogram trigger
hist_register_trigger() puts the trigger on the global named_triggers
list in cmd_ops->init(), and only then sets the trace clock:
if (data->cmd_ops->init) {
ret = data->cmd_ops->init(data);
if (ret < 0)
goto out;
}
if (hist_data->enable_timestamps) {
ret = tracing_set_clock(file->tr, hist_data->attrs->clock);
if (ret) {
hist_err(tr, HIST_ERR_SET_CLOCK_FAIL, errpos(clock));
goto out;
}
The clock string is not checked anywhere before that call, so a named
trigger using common_timestamp with an unknown clock fails after it has
already become findable. event_hist_trigger_parse() then frees it
without taking it off the list, and the next lookup by name reads the
freed object:
~# cd /sys/kernel/tracing/events/sched/sched_switch
~# echo 'hist:name=foo:keys=common_pid:ts=common_timestamp:clock=bogus' > trigger
bash: echo: write error: Invalid argument
~# echo 'hist:name=foo:keys=common_pid' > trigger

Set the clock before the trigger is registered, so that nothing which
can fail runs after it is published, the way commit 6f86bdeab633
("tracing: Fix bad hist from corrupting named_triggers list") moved the
registration below the rest of the setup.
tracing_set_filter_buffering() is reference counted, so the init failure
path has to drop the reference that the clock block now takes first. |
| IBM Guardium Data Protection 12.2 stores internal REST service-account passwords in a reversible plaintext-equivalent format. An authenticated attacker who gains access to the stored credential could recover the password and obtain an administrative REST access token. |
| Apache Airflow's `/assets/events` API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID, run ID and event timestamps — for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later. |
| IBM Guardium Data Protection 12.2 could allow a remote attacker to obtain sensitive information, delete arbitrary files, or execute arbitrary code due to improper limitation of a pathname to a restricted directory. |
| Apache Airflow: the Core API logout endpoint revokes only a session token presented as the _token cookie. When a client logs out presenting its credential as an Authorization bearer header instead, the endpoint returns its normal logout response but revokes nothing, so the token remains valid until it expires. An attacker who already holds a copy of that token keeps the victim's access after the victim has logged out and believes the session ended; the default token lifetime is 24 hours and is configurable.
Affects API clients that authenticate with a bearer token rather than the browser session cookie. The attacker must already possess a copy of a valid token; obtaining one is outside the scope of this issue, and no privileges beyond the victim's own are gained.
Users of apache-airflow are recommended to upgrade to apache-airflow version 3.3.2 or later, which fixes the issue. |

| In the Linux kernel, the following vulnerability has been resolved:
s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly
When hardware persistently returns -EBUSY after exhausting retries,
the error propagates to crypto_finalize_*_request(). The crypto API's
completion wrapper treats -EBUSY as a queueing status and swallows it,
preventing the completion callback from firing. This causes callers
using crypto_wait_req() to block indefinitely.
Translate persistent -EBUSY to -EIO after retry exhaustion to ensure
proper error propagation and callback invocation. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: fib: bound automatic table ID allocation
fib_empty_table() probes every table ID from 1 until it finds a
free one. IPv4 tables are stored in a 256-bucket hash table, so a
dense set of IDs makes each probe walk a growing hash chain while
RTNL is held.
Automatic table assignment ("ip rule ... table 0") is an IPv4-only
legacy path. Bound the automatically allocated ID to 4096 so the
RTNL hold stays bounded, without changing lookups of explicitly
specified table IDs.
This changes user-visible behavior. A table-0 rule previously
received the lowest free ID in 1..RT_TABLE_MAX (0xFFFFFFFF). After
this patch the search stops at 4096 and the rule add fails with
ENOBUFS if that range is fully occupied. Explicit table IDs above
4096 remain usable.
The automatic path is unused in practice: it is IPv4-only, not
documented by ip-rule, uncovered by kernel selftests, and both
NetworkManager and systemd refuse table 0. |
| In the Linux kernel, the following vulnerability has been resolved:
igmp: convert struct ip_sf_list to RCU
Commit 23d2b94043ca ("igmp: Add ip_mc_list lock in ip_check_mc_rcu")
added spin_lock_bh(&im->lock) to ip_check_mc_rcu() to prevent a
use-after-free while iterating im->sources during concurrent deletions.
However, ip_check_mc_rcu() is called from RCU read-side critical
sections in packet receive and route lookup fast paths (e.g.
__mkroute_output(), ip_route_input_rcu(), and __udp4_lib_rcv()).
When igmpv3_send_cr() or igmpv3_send_report() holds &pmc->lock and
calls add_grec() -> igmpv3_newpack() -> ip_route_output_ports(),
an XFRM policy matching a multicast destination triggers
xfrm_tmpl_resolve_one() -> xfrm4_get_saddr() -> __mkroute_output() ->
ip_check_mc_rcu(). This attempts to acquire &im->lock while &pmc->lock
is already held on the same CPU, triggering a lockdep recursive locking
warning / deadlock.
Fix this by converting IPv4 struct ip_sf_list to RCU, mirroring the
IPv6 implementation in net/ipv6/mcast.c:
1. Add struct rcu_head to struct ip_sf_list and annotate sf_next,
sources, and tomb as __rcu pointers.
2. Use rcu_assign_pointer() and kfree_rcu() for list updates and
deletions.
3. Remove spin_lock_bh(&im->lock) from ip_check_mc_rcu() and traverse
im->sources locklessly with for_each_psf_rcu(), reading and writing
counter fields with READ_ONCE() and WRITE_ONCE().
Note: RCU conversion of /proc/net/mcfilter will be done in a
separate patch. |
