Debian DLA-2454-1 : rclone security update

medium Nessus Plugin ID 143099

Language:

Synopsis

The remote Debian host is missing a security update.

Description

golang-go.crypto was recently updated with a fix for CVE-2019-11840.
This in turn requires all 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.

For Debian 9 stretch, this problem has been fixed in version 1.35-1+deb8u1.

We recommend that you upgrade your rclone packages.

For the detailed security status of rclone please refer to its security tracker page at:

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

Solution

Upgrade the affected packages.
