TRAMP is a remote file editing package for GNU Emacs, a highly
|
||
|
|
extensible and customizable text editor.

Stefan Monnier discovered that the tramp-make-tramp-temp-file()
|
||
|
|
function creates temporary files in an insecure manner.

<p>
|
||
|
|
A local attacker could create symbolic links in the directory where the
|
||
|
|
temporary files are written, pointing to a valid file somewhere on the
|
||
|
|
filesystem that is writable by the user running TRAMP. When TRAMP
|
||
|
|
writes the temporary file, the target valid file would then be
|
||
|
|
overwritten with the contents of the TRAMP temporary file.
|
||
|
|

||
|

</impact>
|

|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.

All TRAMP users should upgrade to the latest version:
