Title

SAIL has heap buffer overflow in PSD decoder — bpp mismatch in LAB 16-bit mode

Summary

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit c930284445ea3ff94451ccd7a57c999eca3bc979, the PSD codec computes bytes-per-pixel (`bpp`) from raw header fields `channels * depth`, but the pixel buffer is allocated based on the resolved pixel format. For LAB mode with `channels=3, depth=16`, `bpp = (3*16+7)/8 = 6`, but the format `BPP40_CIE_LAB` allocates only 5 bytes per pixel. Every pixel write overshoots, causing a deterministic heap buffer overflow on every row. Commit c930284445ea3ff94451ccd7a57c999eca3bc979 contains a patch.

CVE-2026-40494 (GCVE-0-2026-40494)

Vulnerability from cvelistv5 – Published: 2026-04-18 01:42 – Updated: 2026-04-20 14:55

Title

SAIL has heap buffer overflow in TGA RLE decoder — raw packet path missing bounds check

Summary

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302, the TGA codec's RLE decoder in `tga.c` has an asymmetric bounds check vulnerability. The run-packet path (line 297) correctly clamps the repeat count to the remaining buffer space, but the raw-packet path (line 305-311) has no equivalent bounds check. This allows writing up to 496 bytes of attacker-controlled data past the end of a heap buffer. Commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302 patches the issue.

CVE-2026-41144 (GCVE-0-2026-41144)

Vulnerability from cvelistv5 – Published: 2026-04-21 23:58 – Updated: 2026-04-22 18:15

Title

F´ (F Prime) has Integer Overflow in FileUplink

Summary

F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to version 4.2.0, the bounds check byteOffset + dataSize > fileSize uses U32 addition that wraps around on overflow. An attacker-crafted DataPacket with byteOffset=0xFFFFFF9C and dataSize=100 overflows to 0, bypassing the check entirely. The subsequent file write proceeds at the original ~4GB offset. Additionally, Svc/FileUplink/File.cpp:20-31 performs no sanitization on the destination file path. Combined, these allow writing arbitrary data to any file at any offset. The impact is arbitrary file write leading to remote code execution on embedded targets. Note that this is a logic bug. ASAN does not detect it because all memory accesses are within valid buffers — the corruption occurs in file I/O. Version 4.2.0 contains a patch. No known workarounds are available.

Severity

CVE-2026-41157 (GCVE-0-2026-41157)

Vulnerability from cvelistv5 – Published: 2026-06-12 21:53 – Updated: 2026-06-16 03:56

Title

GPU DDK - OOB Write in CalculateNPOTTwiddleSparsePageMap3D

Summary

A web page that contains unusual WebGPU content loaded into the GPU GLES render process and can trigger an out-of-bound write in the GPU user-space driver, leading to memory corruption and possible browser/GPU process crash. The software computes a required memory size from untrusted input, but integer overflow can produce a value smaller than needed. Subsequent write operations may then occur past the intended memory boundary, corrupting adjacent memory and causing process instability or termination.

Severity

9.8 (Critical)

CVE-2026-41257 (GCVE-0-2026-41257)

Vulnerability from cvelistv5 – Published: 2026-05-11 17:14 – Updated: 2026-05-11 19:25

Title

jq: Signed-int overflow in `stack_reallocate` (jq VM stack)

Summary

jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB (via deeply nested generator forks), the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for a memmove with attacker-influenced offsets.

Severity

6.4 (Medium)

CVE-2026-41676 (GCVE-0-2026-41676)

Vulnerability from cvelistv5 – Published: 2026-04-24 17:16 – Updated: 2026-04-24 17:43

Title

rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1

Summary

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.27 to before 0.10.78, Deriver::derive (and PkeyCtxRef::derive) sets len = buf.len() and passes it as the in/out length to EVP_PKEY_derive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extract ignore the incoming *keylen, unconditionally writing the full shared secret (32/56/prime-size bytes). A caller passing a short slice gets a heap/stack overflow from safe code. OpenSSL 3.x providers do check, so this only impacts older OpenSSL. This vulnerability is fixed in 0.10.78.

Severity

Mitigation ID: MIT-3

Phase: Requirements

Strategy: Language Selection

Description:

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 ID: MIT-4.1

Phase: Architecture and Design

Strategy: Libraries or Frameworks

Description:

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 ID: MIT-10

Phases: Operation, Build and Compilation

Strategy: Environment Hardening

Description:

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 ID: MIT-9

Phase: Implementation

Description:

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 ID: MIT-11

Phases: Operation, Build and Compilation

Strategy: Environment Hardening

Description:

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 ID: MIT-12

Phase: Operation

Strategy: Environment Hardening

Description:

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 ID: MIT-13

Phase: Implementation

Description:

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