Description

This security bulletin contains information about 1 security vulnerability.


1) Path traversal (CVE-ID: CVE-2019-16777)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. The software fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the first binary. This only affects files in /usr/local/bin

A remote attacker can overwrite arbitrary files on the system.


Remediation

Install update from vendor's website.
