Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in the caml_ba_deserialize function in byterun/bigarray.c in the standard library due to integer overflow when marshalled data is accepted from an untrusted source. A remote attacker can cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
