📄 Samsung QuramDng Malformed DNG TrimBounds Opcode Out‑Of‑Bounds Read

A vulnerability exists in the image decoding logic of Quram DNG parser within libimagecodec.quram.so. The flawed bounds validation in handling TrimBounds opcode triggers out-of-bounds reads on heap-allocated image buffers. This issue allows remote attackers to craft a malicious DNG payload, embed...

📄 Samsung Quram DNG Heap Corruption

Samsung devices utilize Quram's DNG decoder. A malformed ScalePerColumn opcode with oversized areaSpec and extreme pitches leads to arithmetic overflow in the per-column scaling loop. After allocation miscalculation, subsequent writes corrupt heap structures. Carefully crafted payloads enable...

📄 Samsung Quram DNG Advanced Remote Code Execution

This proof of concept uses an advanced exploitation technique that allows a remote attacker to execute arbitrary code on a target device by carefully controlling and manipulating memory in the target application or library. This technique is particularly used against memory-sensitive libraries li...

📄 Samsung QuramDNG Type Confusion Detector Vulnerability Scanner

This C++ scanner analyzes DNG Digital Negative files for the CVE-2025-58478 type confusion vulnerability in the libimagecodec.quram.so library used on Samsung devices...

📄 Samsung Quram DNG Remote Code Execution

A vulnerability exists in Samsung's image decoding library libimagecodec.quram.so responsible for parsing Digital Negatives DNG. A malformed DNG containing oversized IFD entries can cause heap corruption. With precise heap grooming, this condition may lead to remote code execution when the...

📄 Samsung Quram DNG TrimBounds Out-Of-Bounds Read

A vulnerability exists in the image decoding logic of Quram DNG parser within libimagecodec.quram.so. The flawed bounds validation in handling TrimBounds opcode triggers out-of-bounds reads on heap-allocated image buffers. This issue allows remote attackers to craft a malicious DNG payload, embed...
