Denial of service in Google Guava

1) Uncontrolled memory allocation

EUVDB-ID: #VU12886

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-10237

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to unbounded memory allocation. A remote attacker can cause the service to crash and deserialize attacker-provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable.

Mitigation

Update to version 24.1.1.

Vulnerable software versions

Guava: Google Core Libraries For Java: 11.0 - 24.1
