EulerOS 2.0 SP8 : ceph (EulerOS-SA-2021-2288)

medium Nessus Plugin ID 152301

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the ceph packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in the Red Hat Ceph Storage RGW in versions before 14.2.21. When processing a GET Request for a swift URL that ends with two slashes it can cause the rgw to crash, resulting in a denial of service. The greatest threat to the system is of availability.(CVE-2021-3531)

 - A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway) in versions before 14.2.21. The vulnerability is related to the injection of HTTP headers via a CORS ExposeHeader tag. The newline character in the ExposeHeader tag in the CORS configuration file generates a header injection in the response when the CORS request is made. In addition, the prior bug fix for CVE-2020-10753 did not account for the use of \r as a header separator, thus a new flaw has been created.(CVE-2021-3524)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ceph packages.
