CVSS v3.1 |
| Wasmtime is a runtime for WebAssembly. From 32.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Cranelift compilation backend contains a bug on aarch64 when performing a certain shape of heap accesses which means that the wrong address is accessed. When combined with explicit bounds checks a guest WebAssembly module this can create a situation where there are two diverging computations for the same address: one for the address to bounds-check and one for the address to load. This difference in address being operated on means that a guest module can pass a bounds check but then load a different address. Combined together this enables an arbitrary read/write primitive for guest WebAssembly when accesssing host memory. This is a sandbox escape as guests are able to read/write arbitrary host memory. This vulnerability has a few ingredients, all of which must be met, for this situation to occur and bypass the sandbox restrictions. This miscompiled shape of load only occurs on 64-bit WebAssembly linear memories, or when Config::wasm_memory64 is enabled. 32-bit WebAssembly is not affected. Spectre mitigations or signals-based-traps must be disabled. When spectre mitigations are enabled then the offending shape of load is not generated. When signals-based-traps are disabled then spectre mitigations are also automatically disabled. The specific bug in Cranelift is a miscompile of a load of the shape load(iadd(base, ishl(index, amt))) where amt is a constant. The amt value is masked incorrectly to test if it's a certain value, and this incorrect mask means that Cranelift can pattern-match this lowering rule during instruction selection erroneously, diverging from WebAssembly's and Cranelift's semantics. This incorrect lowering would, for example, load an address much further away than intended as the correct address's computation would have wrapped around to a smaller value insetad. This vulnerability is fixed in 36.0.7, 42.0.2, and 43.0.1. |
| Wasmtime is a runtime for WebAssembly. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime with its Winch (baseline) non-default compiler backend may allow properly constructed guest Wasm to access host memory outside of its linear-memory sandbox. This vulnerability requires use of the Winch compiler (-Ccompiler=winch). By default, Wasmtime uses its Cranelift backend, not Winch. With Winch, the same incorrect assumption is present in theory on both aarch64 and x86-64. The aarch64 case has an observed-working proof of concept, while the x86-64 case is theoretical and may not be reachable in practice. This Winch compiler bug can allow the Wasm guest to access memory before or after the linear-memory region, independently of whether pre- or post-guard regions are configured. The accessible range in the initial bug proof-of-concept is up to 32KiB before the start of memory, or ~4GiB after the start of memory, independently of the size of pre- or post-guard regions or the use of explicit or guard-region-based bounds checking. However, the underlying bug assumes a 32-bit memory offset stored in a 64-bit register has its upper bits cleared when it may not, and so closely related variants of the initial proof-of-concept may be able to access truly arbitrary memory in-process. This could result in a host process segmentation fault (DoS), an arbitrary data leak from the host process, or with a write, potentially an arbitrary RCE. This vulnerability is fixed in 36.0.7, 42.0.2, and 43.0.1. |
| Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of transcoding strings between components contains a bug where the return value of a guest component's realloc is not validated before the host attempts to write through the pointer. This enables a guest to cause the host to write arbitrary transcoded string bytes to an arbitrary location up to 4GiB away from the base of linear memory. These writes on the host could hit unmapped memory or could corrupt host data structures depending on Wasmtime's configuration. Wasmtime by default reserves 4GiB of virtual memory for a guest's linear memory meaning that this bug will by default on hosts cause the host to hit unmapped memory and abort the process due to an unhandled fault. Wasmtime can be configured, however, to reserve less memory for a guest and to remove all guard pages, so some configurations of Wasmtime may lead to corruption of data outside of a guest's linear memory, such as host data structures or other guests's linear memories. This vulnerability is fixed in 24.0.7, 36.0.7, 42.0.2, and 43.0.1. |
| Out-of-bounds write vulnerability exists in Ricoh MFPs and printers. If a remote attacker sends a specially crafted request to the affected products, the products may be able to cause a denial-of-service (DoS) condition and/or user's data may be destroyed. |
| We have identified a buffer overflow issue allowing out-of-bounds write when processing LLMNR or mDNS queries with very long DNS names. This issue only affects systems using Buffer Allocation Scheme 1 with LLMNR or mDNS enabled.
Users should upgrade to the latest version and ensure any forked or derivative code is patched to incorporate the new fixes. |
| Simple Startup Manager 1.17 contains a local buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting memory through the 'File' input parameter. Attackers can craft a malicious payload with 268 bytes to trigger code execution, bypassing DEP and overwriting memory addresses to launch calc.exe. |
| Out-of-bounds Write vulnerability in dail8859 NotepadNext (src/lua/src modules). This vulnerability is associated with program files ldebug.C, lvm.C.
This issue affects NotepadNext: through v0.11. |
| Out-of-bounds write in some Intel(R) Graphics Drivers may allow an authenticated user to potentially enable escalation of privilege via local access. |
| Factorio before 1.1.101 allows a crafted server to execute arbitrary code on clients via a custom map that leverages the ability of certain Lua base module functions to execute bytecode and generate fake objects. |
| Out-of-bounds Write vulnerability in Legion of the Bouncy Castle Inc. Bouncy Castle for Java bc-fips on All (API modules). This vulnerability is associated with program files org/bouncycastle/jcajce/provider/BaseCipher.
This issue affects Bouncy Castle for Java: from BC-FJA 2.1.0 through 2.1.0. |
| SAP Web Dispatcher, Internet Communication Manager (ICM), and SAP Content Server allow an unauthenticated user to exploit logical errors that lead to a memory corruption vulnerability. This results in high impact on the availability with no impact on confidentiality or integrity of the application. |
| A denial-of-service security issue exists in the affected product and version. The security issue is caused through CIP communication using crafted payloads. The security issue could result in no CIP communication with 1715 EtherNet/IP Adapter.A restart is required to recover. |
| SAP CommonCryptoLib does not perform necessary boundary checks during pre-authentication parsing of manipulated ASN.1 data over the network. This may result in memory corruption followed by an application crash, hence leading to a high impact on availability. There is no impact on confidentiality or integrity. |
| Out-of-bounds Write vulnerability was discovered in Open Design Alliance Drawings SDK before 2025.10. Reading crafted DWF file and missing proper checks on received SectionIterator data can trigger an unhandled exception. This can allow attackers to cause a crash, potentially enabling a denial-of-service attack (Crash, Exit, or Restart) or possible code execution. |
| Out-of-bounds Write vulnerability in PointCloudLibrary pcl allows Overflow Buffers. Since version 1.14.0, PCL by default uses a zlib installation from the system, unless the user sets WITH_SYSTEM_ZLIB=FALSE. So this potential vulnerability is only relevant if the PCL version is older than 1.14.0 or the user specifically requests to not use the system zlib. |
| VMware ESXi, Workstation, and Fusion contain a heap-overflow vulnerability in the PVSCSI (Paravirtualized SCSI) controller that leads to an out of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox and exploitable only with configurations that are unsupported. On Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed. |
| Out-Of-Bounds Write vulnerability exists in the OBJ file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025. This vulnerability could allow an attacker to execute arbitrary code while opening a specially crafted OBJÂ file. |
| Due to an unchecked buffer length, a specially crafted L2CAP packet can cause a buffer overflow. This buffer overflow triggers an assert, which results in a temporary denial of service.
If a watchdog timer is not enabled, a hard reset is required to recover the device. |
| When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that all image channels have the same pixel type (and size), and that if there are four channels, the first four are "B", "G", "R" and "A". The channel parsing code can be found in decode_header. The buffer td->uncompressed_data is allocated in decode_block based on the xsize, ysize and computed current_channel_offset.
The function dwa_uncompress then assumes at [5] that if there are 4 channels, these are "B", "G", "R" and "A", and in the calculations at [6] and [7] that all channels are of the same type, which matches the type of the main color channels.
If we set the main color channels to a 4-byte type and add duplicate or unknown channels of the 2-byte EXR_HALF type, then the addition at [7] will increment the pointer by 4-bytes * xsize * nb_channels, which will exceed the allocated buffer.
We recommend upgrading to version 8.0 or beyond. |
| When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that the height and width are divisible by 8.
If the height or width of the image is not divisible by 8, the copy loops at [0] and [1] will continue to write until the next multiple of 8.
The buffer td->uncompressed_data is allocated in decode_block based on the precise height and width of the image, so the "rounded-up" multiple of 8 in the copy loop can exceed the buffer bounds, and the write block starting at [2] can corrupt following heap memory.
We recommend upgrading to version 8.0 or beyond. |
