partclone.fat in Partclone before 0.2.88 is prone to a heap-based buffer overflow vulnerability due to insufficient validation of the FAT superblock, related to the mark_reserved_sectors function. An attacker may be able to execute arbitrary code in the context of the user running the affected application.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
