What it is

MOOS ui-moos through 50b9c6c contains a buffer overflow vulnerability in ScopeTabPane.cpp and ScopeGrid.cpp where client and variable names are formatted into fixed 1024-byte buffers using sprintf without length validation. Attackers can supply arbitrarily long MOOS identifiers that overflow the buffers when an operator selects process list entries or pokes variables, enabling code execution.
