Synopsis

A vulnerability has been found in GNOME Autoar that could allow a remote attacker to execute arbitrary code.

Background

GNOME Autoar provides functions and widgets for GNOME applications which want to use archives as a method to transfer directories over the internet.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-arch/gnome-autoar	< 0.3.1	>= 0.3.1	All supported architectures

Description

Workaround

There is no known workaround at this time.

Resolution
