Title

Snap7 through 1.4.3 Out-of-Bounds Write via BRecv and CheckAsBRecvCompletion

Summary

Snap7 through 1.4.3 contains an out-of-bounds write vulnerability in the passive partner that allows a malicious active partner to overflow application buffers by declaring an unvalidated BSend total length. Attackers connecting from the configured peer address can declare up to 65535 bytes and send a short fragment, causing BRecv to memcpy past the buffer and crash or corrupt SCADA, HMI or gateway processes.

CVE-2026-115504 (GCVE-0-2026-115504)

Vulnerability from cvelistv5 – Published: 2026-10-22 19:14 – Updated: 2026-10-22 19:14

Title

CFITSIO through 4.7.0 Out-of-Bounds Write via ffgcls2 in getcols.c

Summary

CFITSIO through 4.7.0 contains an out-of-bounds write vulnerability in ffgcls2() in getcols.c that trusts attacker-controlled heap descriptor lengths for variable-length string columns. Attackers can supply a crafted FITS file that overflows a fixed 28,800-byte stack buffer and the caller's string array, enabling arbitrary code execution.

Wasmtime before 24.0.12, 25.0.0 before 36.0.13, 37.0.0 before 46.0.2, and 47.0.0 before 47.0.3 contains a type confusion vulnerability because several Store APIs fail to validate that objects belong to the Store's Engine. Embedders mixing objects between Engines via Instance::new, StructRefPre::new, or Tag::new can trigger trampoline signature mismatches causing out-of-bounds stack writes, GC heap corruption, or panics.

CVE-2026-114458 (GCVE-0-2026-114458)

Vulnerability from cvelistv5 – Published: 2026-10-22 06:37 – Updated: 2026-10-22 06:37

Title

Mod_qos: undersized connection-monitor scratch array permits heap buffer overflow

Summary

A flaw was found in mod_qos. An unauthenticated remote attacker can cause a Denial of Service (DoS) by maintaining numerous concurrent low-rate connections to a target server. When connection rate monitoring is active, the module fails to verify array boundaries when recording client IP addresses, allowing more connection records to be added than the allocated buffer can hold. This issue leads to heap memory corruption, which can crash the web server process.

Severity

5.9 (Medium)

CVE-2026-113679 (GCVE-0-2026-113679)

Vulnerability from cvelistv5 – Published: 2026-10-20 15:40 – Updated: 2026-10-20 16:21

Title

HarfBuzz 8.0.0 through 14.6.0 Out-of-Bounds Write via WebAssembly font_glyph_to_string

Summary

HarfBuzz 8.0.0 through 14.6.0 contains an out-of-bounds write vulnerability in the experimental WebAssembly shaper because the font_glyph_to_string import has a wrong WAMR signature. Attackers can supply a crafted font whose wasm module places the output buffer near linear memory's end, writing glyph-name bytes into host memory to crash or corrupt applications.

CVE-2026-112398 (GCVE-0-2026-112398)

Vulnerability from cvelistv5 – Published: 2026-10-19 21:07 – Updated: 2026-10-22 21:06

Title

Pillow: Heap buffer overflow in FlashPix (FPX) JPEG decoding leads to code execution

Summary

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's FlashPix JPEG-tile decoder can write decoded scanlines beyond the allocated tile buffer. FlashPix (FPX) JPEG decoding selects raw mode LA with two bytes per pixel, while an unrecognized JPEG mode can be decoded as JCS_UNKNOWN with four components, causing ImagingJpegDecode to write four-component scanlines into the two-byte tile buffer. An attacker can supply a crafted OLE2 FlashPix file to an application with the optional olefile dependency installed that opens or thumbnails untrusted input. This can corrupt heap memory and may allow arbitrary code execution. This issue is fixed in version 13.0.0.

Severity

9.2 (Critical)

Vulnerability from cvelistv5 – Published: 2026-10-19 21:17 – Updated: 2026-10-19 21:38

Title

Pillow: Out-of-bounds access in _imagingmorph on a zero-width image

Summary

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's ImageMorph.MorphOp.apply() can access memory before a row buffer for a zero-width image. PPM and PGM input can create an image with width zero, and the native morphology routine indexes outrow[width - 1] without rejecting that geometry. An attacker can supply such an image to an application that applies a morphology operation. This can crash the process. This issue is fixed in version 13.0.0.

Severity

8.7 (High)

Title

Netpbm through 11.16.00 Heap Out-of-Bounds Write via rasttopnm pr_load_image

Summary

Netpbm through 11.16.00 contains a heap out-of-bounds write vulnerability in the rasttopnm Sun rasterfile run-length decoder pr_load_image in converter/other/rast.c. Attackers can supply a byte-encoded rasterfile with tiny dimensions and a long run-length body to write controlled bytes past md_image, causing memory corruption and crashes.

CVE-2026-112060 (GCVE-0-2026-112060)

Vulnerability from cvelistv5 – Published: 2026-10-18 12:19 – Updated: 2026-10-19 16:12

Title

librtmp (RTMPDump) through 2.6 Heap Out-of-Bounds Write via AMF3_Decode

Summary

librtmp in RTMPDump through 2.6 contains an out-of-bounds read and heap out-of-bounds write vulnerability because AMF3_Decode ignores AMF3 property decode failures.

CVE-2026-112059 (GCVE-0-2026-112059)

Vulnerability from cvelistv5 – Published: 2026-10-18 12:19 – Updated: 2026-10-22 02:19 Unsupported When Assigned

Title

libLAS through 1.8.1 Heap Out-of-Bounds Write via LASSchema VLR

Summary

libLAS through 1.8.1 contains a heap out-of-bounds write vulnerability in the point record reader caused by truncating the schema byte size to 16 bits when sizing the point buffer. Attackers can craft a .las file with a LASSchema variable length record whose schema exceeds 65535 bytes, so tools like lasinfo, las2las, or las2txt write attacker-controlled bytes past the heap buffer, causing memory corruption and crashes.

Severity

Mitigation MIT-3

Requirements

Strategy: Language Selection

Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer.
Be wary that a language's interface to native code may still be subject to overflows, even if the language itself is theoretically safe.

Mitigation MIT-4.1

Architecture and Design

Strategy: Libraries or Frameworks

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Examples include the Safe C String Library (SafeStr) by Messier and Viega [REF-57], and the Strsafe.h library from Microsoft [REF-56]. These libraries provide safer versions of overflow-prone string-handling functions.

Mitigation MIT-10

Operation Build and Compilation

Strategy: Environment Hardening

Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.

Mitigation MIT-9

Implementation

Consider adhering to the following rules when allocating and managing an application's memory:
Double check that the buffer is as large as specified.
When using functions that accept a number of bytes to copy, such as strncpy(), be aware that if the destination buffer size is equal to the source buffer size, it may not NULL-terminate the string.
Check buffer boundaries if accessing the buffer in a loop and make sure there is no danger of writing past the allocated space.
If necessary, truncate all input strings to a reasonable length before passing them to the copy and concatenation functions.

Mitigation MIT-11

Operation Build and Compilation

Strategy: Environment Hardening

Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].

Mitigation MIT-12

Operation

Strategy: Environment Hardening

Use a CPU and operating system that offers Data Execution Protection (using hardware NX or XD bits) or the equivalent techniques that simulate this feature in software, such as PaX [REF-60] [REF-61]. These techniques ensure that any instruction executed is exclusively at a memory address that is part of the code segment.
For more information on these techniques see D3-PSEP (Process Segment Execution Prevention) from D3FEND [REF-1336].

Mitigation MIT-13

Implementation

Replace unbounded copy functions with analogous functions that support length arguments, such as strcpy with strncpy. Create these if they are not available.
