New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Debian host is missing a security update.

Description

Three issues have been found in golang-1.8, a Go programming language compiler version 1.8

CVE-2020-15586 Using the 100-continue in HTTP headers received by a net/http/Server can lead to a data race involving the connection's buffered writer.

CVE-2020-16845 Certain invalid inputs to ReadUvarint or ReadVarint could cause those functions to read an unlimited number of bytes from the ByteReader argument before returning an error.

CVE-2020-28367 When using cgo, arbitrary code might be executed at build time.

For Debian 9 stretch, these problems have been fixed in version 1.8.1-1+deb9u2.

We recommend that you upgrade your golang-1.8 packages.

For the detailed security status of golang-1.8 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/golang-1.8

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.
