"value": "USB Test is a lightweight Windows CLI utility for verifying sector integrity and detecting overreported capacity on USB flash drives. Prior to version 1.1.5, getSectorSize() in USB Test/src/driveinfo.cpp trusts DISK_GEOMETRY.BytesPerSector returned by IOCTL_DISK_GET_DRIVE_GEOMETRY without checking whether the call succeeded or enforcing size bounds. USB Test/src/drivetest.cpp uses the value for division and to size a heap buffer before memcpy(buffer.data(), §or, 8), so a physically connected malicious USB storage device can report a value below eight bytes and cause repeated out-of-bounds writes, or report zero and cause a divide-by-zero denial of service when a user starts a drive test. The heap corruption can crash the elevated application and may permit arbitrary code execution. This issue is fixed in version 1.1.5."
