IBM Db2 for Linux 12.1.0, 12.1.1, and 12.1.2 is vulnerable to a denial of service as the server may crash under certain conditions with a specially crafted query.

Weakness

The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
