Description

The remote host is affected by the vulnerability described in GLSA-202402-20 (Thunar: Arbitrary Code Execution)

 - An issue was discovered in Thunar before 4.16.7 and 4.17.x before 4.17.2. When called with a regular file as a command-line argument, it delegates to a different program (based on the file type) without user confirmation. This could be used to achieve code execution. (CVE-2021-32563)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All Thunar users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=xfce-base/thunar-4.17.3
