Synopsis
A vulnerability has been discovered in Thunar which may lead to
arbitrary code execution
Background
Thunar is a modern file manager for the Xfce Desktop Environment. Thunar
has been designed from the ground up to be fast and easy to use. Its
user interface is clean and intuitive and does not include any confusing
or useless options by default. Thunar starts up quickly and navigating
through files and folders is fast and responsive.
Affected Packages
Package Vulnerable Unaffected
---------------- ------------ ------------
xfce-base/thunar < 4.17.3 >= 4.17.3
Impact
When called with a regular file as command line argument, Thunar
would delegate to some other program without user confirmation
based on the file type. This could be exploited to trigger code
execution in a chain of vulnerabilities.
Workaround
There is no known workaround at this time.
