Debian LTS: Security Advisory for rclone (DLA-2454-1)

Published: 2020-11-19 04:00:08
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:P/I:N/A:N

Summary:
The remote host is missing an update for the 'rclone' Linux Distribution Package(s) announced via the DLA-2454-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
golang-go.crypto was recently updated with a fix for CVE-2019-11840. This in turn requires all Linux Distribution Packages that use the affected code to be recompiled in order to pick up the security fix. CVE-2019-11840 An issue was discovered in supplementary Go cryptography libraries, aka golang-googlecode-go-crypto. If more than 256 GiB of keystream is generated, or if the counter otherwise grows greater than 32 bits, the amd64 implementation will first generate incorrect output, and then cycle back to previously generated keystream. Repeated keystream bytes can lead to loss of confidentiality in encryption applications, or to predictability in CSPRNG applications.

Affected Versions:
'rclone' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 9 stretch, this problem has been fixed in version 1.35-1+deb8u1. We recommend that you upgrade your rclone Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
