#VU12886 Uncontrolled memory allocation in Guava: Google Core Libraries For Java - CVE-2018-10237

Vulnerability identifier: #VU12886

Vulnerability risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-10237

CWE-ID: CWE-789

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Guava: Google Core Libraries For Java
Universal components / Libraries / Libraries used by multiple products

Vendor: Google

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
