CVSS v3.1 |
| 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. |
| NVIDIA nvJPEG2000 library contains a vulnerability where an attacker can cause an out-of-bounds write issue by means of a specially crafted JPEG2000 file. A successful exploit of this vulnerability might lead to code execution and data tampering. |
| 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. |
| 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 parsing the header for a DHAV file, there's an integer underflow in offset calculation that leads to reading the duration from before the start of the allocated buffer.
If we load a DHAV file that is larger than MAX_DURATION_BUFFER_SIZE bytes (0x100000) for example 0x101000 bytes, then at [0] we have size = 0x101000. At [1] we have end_buffer_size = 0x100000, and at [2] we have end_buffer_pos = 0x1000.
The loop then scans backwards through the buffer looking for the dhav tag; when it is found, we'll calculate end_pos based on a 32-bit offset read from the buffer.
There is subsequently a check [3] that end_pos is within the section of the file that has been copied into end_buffer, but it only correctly handles the cases where end_pos is before the start of the file or after the section copied into end_buffer, and not the case where end_pos is within the the file, but before the section copied into end_buffer. If we provide such an offset, (end_pos - end_buffer_pos) can underflow, resulting in the subsequent access at [4] occurring before the beginning of the allocation.
We recommend upgrading to version 8.0 or beyond. |
| When calculating the content path in handling of MPEG-DASH manifests, there's an out-of-bounds NUL-byte write one byte past the end of the buffer.When we call xmlNodeGetContent below [0], it returns a buffer precisely allocated to match the string length, using strdup internally. If this buffer is not an empty string, it is assigned to root_url at [1].If the last (non-NUL) byte in this buffer is not '/' then we append '/' in-place at [2]. This will write two bytes into the buffer, starting at the last valid byte in the buffer, writing the NUL byte beyond the end of the allocated buffer.
We recommend upgrading to version 8.0 or beyond. |
| Insufficient parameter sanitization in TEE SOC Driver could allow an attacker to issue a malformed DRV_SOC_CMD_ID_SRIOV_SPATIAL_PART and cause read or write past the end of allocated arrays, potentially resulting in a loss of platform integrity or denial of service. |
| A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot information, which can be used to by-pass secure boot protections. |
| COMMAX UMS Client ActiveX Control 1.7.0.2 contains a heap-based buffer overflow vulnerability that allows attackers to execute arbitrary code by providing excessively long string arrays through multiple functions. Attackers can exploit improper boundary validation in CNC_Ctrl.dll to cause heap corruption and potentially gain system-level access. |
| A heap-based memory vulnerability has been identified in the Postscript interpreter in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code. |
| Out-of-bounds write in the Intel(R) 800 Series Ethernet Driver for Intel(R) Ethernet Adapter Complete Driver Pack before versions 29.1 may allow an unauthenticated user to potentially enable denial of service via adjacent access. |
| DjVuLibre is a GPL implementation of DjVu, a web-centric format for distributing documents and images. Prior to version 3.5.29, the MMRDecoder::scanruns method is affected by an OOB-write vulnerability, because it does not check that the xr pointer stays within the bounds of the allocated buffer. This can lead to writes beyond the allocated memory, resulting in a heap corruption condition. An out-of-bounds read with pr is also possible for the same reason. This issue has been patched in version 3.5.29. |
| Software installed and run as a non-privileged user may conduct improper GPU system calls resulting in platform instability and reboots. |
| Heap-based Buffer Overflow, Memory Corruption, Out-Of-Bounds Read, Out-Of-Bounds Write, Stack-based Buffer Overflow, Type Confusion, Uninitialized Variable, Use-After-Free vulnerabilities exist in the file reading procedure in SOLIDWORKS Desktop on Release SOLIDWORKS 2024.
These vulnerabilities could allow an attacker to execute arbitrary code while opening a specially crafted CATPART, DWG, DXF, IPT, JT, SAT, SLDDRW, SLDPRT, STL, STP, X_B or X_T file. |
| Velocidex WinPmem versions below 4.1 suffer from an Out of Bounds Write vulnerability. By using an IO Control, a user space program can trick the driver into writing a 0 into any chosen memory location. In conjunction with information leakage from the WinPmem driver, attackers can discover the location in memory for the g_CiOptions global symbol. This can be leveraged to disable signed driver enforcement on the target system - allowing attackers to load unsigned drivers. |
| Contec Health CMS8000 Patient Monitor is vulnerable to an out-of-bounds write, which could allow an attacker to send specially formatted UDP requests in order to write arbitrary data. This could result in remote code execution. |

| An out-of-bounds write flaw was found in mpg123 when handling crafted streams. When decoding PCM, the libmpg123 may write past the end of a heap-located buffer. Consequently, heap corruption may happen, and arbitrary code execution is not discarded. The complexity required to exploit this flaw is considered high as the payload must be validated by the MPEG decoder and the PCM synth before execution. Additionally, to successfully execute the attack, the user must scan through the stream, making web live stream content (such as web radios) a very unlikely attack vector. |
| 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. |
