2) Memory corruption

EUVDB-ID: #VU17097

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-16846

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists in the RADOS Gateway (RGW) code base due to boundary error in the ListBucket max-keys function during bucket listing operations. A remote attacker with Ceph RGW user permissions can trigger memory corruption and perform a denial of service attack against object maps (OMAPs) holding bucket indexes.

Mitigation

Install updates from vendor's website.
