No public exploit identified at time of analysis.

A heap buffer overflow vulnerability exists in the DICOM image decoder. Dimension fields are encoded using Value Representation (VR) Unsigned Long (UL), instead of the expected VR Unsigned Short (US), which allows extremely large dimensions to be processed. This causes an integer overflow during frame size calculation and results in out-of-bounds memory access during image decoding.

Privilege escalation in Windows 11 (24h2, 26h1) and Windows Server 2022 (23h2) via heap overflow allows authenticated local users to gain system-level access. The vulnerability requires valid credentials but no user interaction, making it a direct path to complete system compromise. No patch is currently available.

Privilege escalation in Azure Linux Virtual Machines results from a heap-based buffer overflow that authenticated local users can exploit to gain elevated system access. An attacker with valid credentials can trigger memory corruption to bypass privilege restrictions and assume administrative control of the affected virtual machine. No patch is currently available, making this a critical risk for organizations running Azure Linux infrastructure.

Medium severity vulnerability in ImageMagick. A 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur.
