Buffer overflow in the PATinst function in src/load_pat.cpp in libmodplug before 0.8.7 allows user-assisted remote attackers to cause a denial of service and possibly execute arbitrary code via a long instrument name.
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.
