mapserv.c in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 does not ensure that the string holding the id parameter ends in a '\0' character, which allows remote attackers to conduct buffer-overflow attacks or have unspecified other impact via a long id parameter in a query action.
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.
