Description
Integer wraparound in multiple server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This can lead to arbitrary code execution as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the input provider may cause a segmentation fault, which is an error occurring when a program attempts to access a memory location that it is not allowed to access.
