CVE-2026-23530

FreeRDP has heap-buffer-overflow in planar_decompress_plane_rle

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0,`freerdp_bitmap_decompress_planar` does not validate `nSrcWidth`/`nSrcHeight` against `planar->maxWidth`/`maxHeight` before RLE decode. A malicious server can trigger a client‑side heap buffer overflow, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.

FreeRDP has heap-buffer-overflow in clear_decompress

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, in ClearCodec, when `glyphData` is present, `clear_decompress` calls `freerdp_image_copy_no_overlap` without validating the destination rectangle, allowing an out-of-bounds read/write via crafted RDPGFX surface updates. A malicious server can trigger a client‑side heap buffer overflow, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.

FreeRDP has heap-buffer-overflow in clear_decompress_residual_data

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a client-side heap buffer overflow occurs in the RDPGFX ClearCodec decode path when maliciously crafted residual data causes out-of-bounds writes during color output. A malicious server can trigger a client‑side heap buffer overflow, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.

FreeRDP has heap-buffer-overflow in Glyph_Alloc

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, FastGlyph parsing trusts `cbData`/remaining length and never validates against the minimum size implied by `cx/cy`. A malicious server can trigger a client‑side global buffer overflow, causing a crash (DoS). Version 3.21.0 contains a patch for the issue.

Heap buffer overflow with attacker-controlled data in XBM parser

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-13 and 6.9.13-38, a heap buffer overflow vulnerability in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file. Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines. Versions 7.1.2-13 and 6.9.13-38 fix the issue.

iccDEV has Heap Buffer Overflow in icCurvesFromXml()

iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. Versions 2.3.1.1 and below have aHeap Buffer Overflow vulnerability in the CIccTagXmlSegmentedCurve::ToXml() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and Code Execution. This issue has been fixed in version 2.3.1.2.

iccDEV has a heap-buffer-overflow in icXmlParseTextString()

iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, a heap buffer over-read when the strlen() function attempts to read a non-null-terminated buffer potentially leaking heap memory contents and causing application termination. This vulnerability affects users of the iccDEV library who process ICC color profiles. ICC Profile Injection vulnerabilities arise when user-controllable input is incorporated into ICC profile data or other structured binary blobs in an unsafe manner. Version 2.3.1.2 contains a fix for the issue. No known workarounds are available.

bulk_extractor has Heap-based Buffer Overflow vulnerability

`bulk_extractor` is a digital forensics exploitation tool. Starting in version 1.4, `bulk_extractor`’s embedded unrar code has a heap‑buffer‑overflow in the RAR PPM LZ decoding path. A crafted RAR inside a disk image causes an out‑of‑bounds write in `Unpack::CopyString`, leading to a crash under ASAN (and likely a crash or memory corruption in production builds). There's potential for using this for RCE. As of time of publication, no known patches are available.

OpenFGA Improper Policy Enforcement

OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA v1.8.5 to v1.11.2 ( openfga-0.2.22<= Helm chart <= openfga-0.2.51, v.1.8.5 <= docker <= v.1.11.2) are vulnerable to improper policy enforcement when certain Check calls are executed. The vulnerability requires a model that has a a relation directly assignable by a type bound public access and assignable by type bound non-public access, a tuple assigned for the relation that is a type bound public access, a tuple assigned for the same object with the same relation that is not type bound public access, and a tuple assigned for a different object that has an object ID lexicographically larger with the same user and relation which is not type bound public access. This vulnerability is fixed in v1.11.3.
