Remote code execution via TIFF heap overflow
Published Jul 10, 2026 · Updated Jul 10, 2026
Out-of-bounds write in Samsung Mobile Devices on Android 14 through 16 allows remote attackers to corrupt memory via a crafted TIFF file. libimagecodec.media.quram.so copies attacker-controlled TIFF data into a heap buffer without validating its declared length. On Galaxy S25 devices, exploitation requires the target to visit a malicious page or open a malicious file and runs code in the current process.
