Details

Phoenix Contact Classic Automation Worx Software Suite in Version 1.87 and below is affected by a remote code execution vulnerability. Manipulated PC Worx or Config+ projects could lead to a remote code execution when unallocated memory is freed because of incompletely initialized data. The attacker needs to get access to an original bus configuration file (*.bcp) to be able to manipulate data inside. After manipulation the attacker needs to exchange the original file by the manipulated one on the application programming workstation. Availability, integrity, or confidentiality of an application programming workstation might be compromised by attacks using these vulnerabilities. Automated systems in operation which were programmed with one of the above-mentioned products are not affected.

Summary
Invalid drop of partially-initialized instances in the pooling instance allocator for modules with defined `externref` globals
Details

Impact

There exists a bug in the pooling instance allocator in Wasmtime's runtime where a failure to instantiate an instance for a module that defines an externref global will result in an invalid drop of a VMExternRef via an uninitialized pointer.

As instance slots may be reused between consecutive instantiations, the value of the uninitialized pointer may be from a previous instantiation and therefore under the control of an attacker via a module's initial values for its globals. If the attacker can somehow determine an address under their control inside the mapped memory representing the instance pool, it is possible to trick the runtime to call drop_in_place on a trait object under the attacker's control and therefore cause remote code execution.

Exploiting the bug to cause remote code execution would be very difficult as attackers cannot determine the addresses of globals from code executing within the WebAssembly VM and the memory space for the instance pool cannot be statically determined. Operating system mitigations, such as address space layout randomization, would additionally increase the difficulty for attackers to determine useful executable code to target with an exploit. It is also very unlikely that attackers will be able to directly influence the conditions that trigger the bug as described below.

When the conditions to trigger the bug are met, however, it is much easier to exploit this bug to cause a denial of service by crashing the host with an invalid memory read.

The following engine configuration (via Config) is required to be impacted by this bug:

  • support for the reference types proposal must be enabled (this is the default for Config).
  • a pooling allocation strategy must be configured via Config::allocation_strategy, which is not the default allocation strategy.

A module must be instantiated with all the following characteristics:

  • The module defines at least one table or memory.
  • The module defines at least one externref global.

During instantiation, one of the following must occur to cause the instantiation to fail:

  • a call to mprotect or VirtualAlloc fails (e.g. out-of-memory conditions).
  • a resource limiter was configured in the associated Store (via Store::limiter or Store::limiter_async) and the limiter returns false from the initial call to memory_growing or table_growing. Stores do not have a resource limiter set by default.

This results in a partially-initialized instance being dropped and that attempts to drop the uninitialized VMExternRef representing the defined externref global.

We have reason to believe that the effective impact of this bug is relatively small because the usage of externref is still uncommon and without a resource limiter configured on the Store, which is not the default configuration, it is only possible to trigger the bug from an error returned by mprotect or VirtualAlloc.

Note that on Linux with the uffd feature enabled, it is only possible to trigger the bug from a resource limiter as the call to mprotect is skipped; if no resource limiter is used, then this configuration is not vulnerable.

Patches

The bug has been fixed in 0.34.1 and 0.33.1; users are encouraged to upgrade as soon as possible.

Workarounds

If it is not possible to upgrade to 0.34.1 or 0.33.1 of the wasmtime crate, it is recommend that support for the reference types proposal be disabled by passing false to Config::wasm_reference_types.

Doing so will prevent modules that use externref from being loaded entirely.

Vulnerability from github – Published: 2025-05-29 15:31 – Updated: 2025-12-16 21:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

module: ensure that kobject_put() is safe for module type kobjects

In 'lookup_or_create_module_kobject()', an internal kobject is created using 'module_ktype'. So call to 'kobject_put()' on error handling path causes an attempt to use an uninitialized completion pointer in 'module_kobject_release()'. In this scenario, we just want to release kobject without an extra synchronization required for a regular module unloading process, so adding an extra check whether 'complete()' is actually required makes 'kobject_put()' safe.

GHSA-8QXC-57HF-HC9J

Vulnerability from github – Published: 2026-07-01 17:48 – Updated: 2026-07-01 17:48
VLAI
Summary
Open Babel has uninitialized pointer dereference in PQS pFormat
Details

Summary

A memory-safety vulnerability in Open Babel's PQS parser caused an uninitialized pointer dereference when reading a crafted input file.

Details

The flaw was in the pFormat handling of the PQS reader. A malformed input caused the parser to dereference a format pointer that had never been initialized.

Impact

Open Babel is a C++ library and CLI used to read and write chemistry file formats; it is shipped by Linux distributions and embedded in services that may parse untrusted input. Triggering this vulnerability requires the victim to open a malicious PQS file with the obabel tool, the OBConversion API, or any of the language bindings (Python, Ruby, Java, R, Perl, C#, PHP).

Affected versions

All releases up to and including 3.1.1.

Patched version

3.2.0 (released 2026-05-26).

Patch

Fix commit: https://github.com/openbabel/openbabel/commit/2a7d2cda

A minimized reproducer for this CVE is checked in under test/files/fuzz_regress/ and is exercised on every CI build under ASAN+UBSAN by the fuzzregresstest harness.

Credit

Reported by Cisco TALOS.
