CVSS v3.1 |
| Urwid is a console user interface library for Python. Prior to 4.0.7, handle_short_request() in urwid/display/web.py performs unguarded character encoding on POST input and unguarded UTF-8 decoding on polling update socket output. A remote attacker who obtains a valid X-Urwid-ID session token can submit non-ASCII POST data that raises UnicodeEncodeError, while non-UTF-8 polling output raises UnicodeDecodeError, causing the CGI handler to return an error and terminate request processing. The POST exception path also leaves an opened file descriptor unclosed for the CGI process lifetime, so repeated requests can cause denial of service for the web display interface. This issue is fixed in version 4.0.7. |
| In BuildKit versions v0.26.0 through v0.34.1, a specific build definition that resolves metadata for the same Git source reference twice can cause the BuildKit daemon to panic and crash, interrupting builds handled by that daemon. The issue is fixed in v0.34.2. |
| tsParticles is a TypeScript library for creating highly customizable particle animations. Prior to 4.3.1, the HTTP mode of @tsparticles/mcp-server calls JSON.parse outside a request-local error boundary in the POST /mcp handler in integrations/mcp-server/src/index.ts. A single unauthenticated malformed JSON body raises a SyntaxError that terminates the Node.js process, leaving the MCP service unavailable until an external supervisor restarts it. This issue is fixed in version 4.3.1. |
| Improper input validation vulnerability in Apache ActiveMQ, Apache ActiveMQ KahaDB.
A user can create a durable subscription with a clientId and subscription name that have a combined length > 65,535 (while separately being shorter) on a broker using KahaDB which can cause the broker to shutdown and be unrecoverable.
This issue affects Apache ActiveMQ: from 6.0.0 before 6.3.3, before 5.19.12; Apache ActiveMQ KahaDB: from 6.0.0 before 6.3.3, before 5.19.12.
Users are recommended to upgrade to version 6.4.0, 6.3.3 or 5.19.12, which fixes the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: nSVM: Triple fault if restore host CR3 fails on nested #VMEXIT
If loading L1's CR3 fails on a nested #VMEXIT, nested_svm_vmexit()
returns an error code that is ignored by most callers, and continues to
run L1 with corrupted state. A sane recovery is not possible in this
case, and HW behavior is to cause a shutdown. Inject a triple fault
instead, and do not return early from nested_svm_vmexit(). Continue
cleaning up the vCPU state (e.g. clear pending exceptions), to handle
the failure as gracefully as possible.
From the APM:
Upon #VMEXIT, the processor performs the following actions in order to
return to the host execution context:
...
if (illegal host state loaded, or exception while loading host state)
shutdown
else
execute first host instruction following the VMRUN
Remove the return value of nested_svm_vmexit(), which is mostly
unchecked anyway. |
| An integer underflow vulnerability in the Avast Windows Filtering Platform (WFP) stream parser on Windows allows denial of service by causing a system crash.
The WFP callout driver processes network stream data and computes length values for packet fragment reassembly. The length calculation does not properly validate input stream sizes against expected boundaries. When processing specially crafted input, the length computation underflows, resulting in allocation or buffer access with an extremely large wrapped-around size value.
The underflow can be triggered remotely via network traffic destined for the filtered port, or locally via crafted data provided to the filtering interface. The resulting memory allocation failure or out-of-bounds access causes a kernel panic and system crash. |
| Missing exception handlers in AvastSvc native message dispatcher (ashServ.dll) on Windows allow a local, unprivileged attacker to crash the service by sending specially crafted JSON messages.
The vulnerability spans multiple handler pathways in the RPC-based native message protocol:
* Log_NmSvc.message handler: converts JSON fields to strings without type validation and without exception boundaries.
* OpenInSz_NmSvc handler: converts URL and origin fields to strings without type checking, exposing an exception.
* OpenInSz_NmSvc.profile handler: converts the profile field to an integer without validation.
In all three cases, the exceptions are not caught by action-specific handlers and propagate up the dispatcher. The common root cause is the absence of try-catch blocks around JSON type conversions in the native message processing chain. |
| An Uncaught Exception vulnerability [CWE-248] vulnerability in Fortinet FortiSandbox 5.2.0 through 5.2.1, FortiSandbox 5.0.0 through 5.0.6, FortiSandbox 4.4 all versions may allow a privileged attacker to deny access to the GUI and CLI persistently via crafted HTTP requests. |
| undici is an HTTP client for Node.js. In versions 7.0.0 through 7.30.1 and 8.0.0 through 8.12.3, when the cache interceptor is composed with a downstream handler that throws during response processing (such as the built-in dump interceptor exceeding its maxSize, or the decompress interceptor rejecting more than five Content-Encoding values), a throw raised asynchronously while a cached response is replayed escapes as an uncaught exception or unhandled promise rejection and terminates the Node.js process. A malicious or compromised HTTP server can crash any such client by serving a cacheable response that triggers the throw on replay, including on a 304 revalidation of a stale entry, so the impact is availability only. The issue is fixed in undici 7.30.2 and 8.12.4, and users should upgrade to one of those versions or later. As a workaround, avoid composing the cache interceptor with a response handler that throws during response processing until upgrading. |
| Incorrect operator (CWE-480) in the FetchSnapshot RPC handler
in Apache Kafka from 2.8.0 before 4.2.2, and from 4.3.0 before 4.3.2
on all platforms allows an authenticated attacker with
CLUSTER_ACTION privilege to cause a denial of service
(controller process termination) via a crafted
FetchSnapshotRequest with an empty topics array or a topic
with no partitions.
Users are recommended to upgrade to version 4.2.2, 4.3.2, or
4.4.0, which fix this issue. Users on unsupported branches
(4.1.x and earlier) should upgrade to 4.2.2 or later. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/mm: Add missing secure storage access fixups for donated memory
There are special cases where secure storage access exceptions happen
in a kernel context for pages that don't have the PG_arch_1 bit
set. That bit is set for non-exported guest secure storage (memory)
but is absent on storage donated to the Ultravisor since the kernel
isn't allowed to export donated pages.
Prior to this patch we would try to export the page by calling
arch_make_folio_accessible() which would instantly return since the
arch bit is absent signifying that the page was already exported and
no further action is necessary. This leads to secure storage access
exception loops which can never be resolved.
With this patch we unconditionally try to export and if that fails we
fixup. |
| A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job. |
| In multiple locations, there is a possible permission bypass due to an uncaught exception. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| Envoy is a cloud-native, open source edge and service proxy. Due to how Envoy invoked the nlohmann JSON library, the library could throw an uncaught exception from downstream data if incomplete UTF-8 strings were serialized. The uncaught exception would cause Envoy to crash. |
| Kyverno before 1.19.2 contains an unchecked type assertion in buildStatementMap that allows unauthenticated attackers to crash the policy engine via crafted attestation statements. Attackers can push an OCI referrer manifest with a non-string type field to bypass image verification under failurePolicy Ignore or crash-loop the reports-controller. |
| Kyverno before 1.19.2 contains a denial-of-service vulnerability in the In and NotIn operators that allows attackers to crash the policy engine via an unchecked type assertion. Attackers can submit resources whose JMESPath-evaluated values yield arrays of integers, booleans, or mixed types, triggering a panic that disrupts admission control and policy enforcement. |
| Kyverno before 1.19.2 contains an unchecked type assertion in its variable-substitution engine that allows users who can submit resources to crash the policy engine. Attackers can submit resources with non-string fields referenced by {{- variable }} shallow substitution in policies, causing a panic that yields webhook denial of service and policy bypass under failurePolicy Ignore. |
| Aedes is an MQTT broker that can run on any stream server. Prior to 1.1.1, the MQTT broker does not bound topic depth or structural complexity before passing topics through `mqemitter` into `qlobber`. A `PUBLISH`, `SUBSCRIBE`, or registered `Will` message containing an excessively deep topic can reach `qlobber._split_words` in `lib/qlobber.js` and trigger an uncaught `too many words` exception. Calls from `handlers/subscribe.js` and the publishing logic are not protected against that exception, so it escapes to the `Node.js event loop` and terminates the entire broker. The `Will` path is independently reachable when a client disconnects ungracefully: it calls `broker.publish` directly and bypasses the `PUBLISH` handler. An attacker must be able to establish an `MQTT session`, authenticated or unauthenticated according to broker configuration. A successful attack disconnects all legitimate clients and prevents reconnection until the broker process restarts. This issue is fixed in version 1.1.1. |
| A flaw was found in the mod_auth_openidc module for Apache httpd. This flaw allows a remote, unauthenticated attacker to trigger a denial of service by sending an empty POST request when the OIDCPreservePost directive is enabled. The server crashes consistently, affecting availability. |
| A NULL pointer dereference vulnerability in WatchGuard Fireware OS’s management interface allows a remote, unauthenticated attacker with network access to the management interface to crash the management service by sending a specially crafted login request. Repeated exploitation terminates all active administrator sessions and in-progress management operations and can prevent management of the device. Traffic processing is not affected. |
