Fedora 26 update for guava

1) Uncontrolled memory allocation

EUVDB-ID: #VU12886

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 - 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

Install updates from vendor's repository.
