Erich Schubert from Debian discovered that unp does not escape file
|
||
|
|
names properly before passing them to calls of the shell.

|

|
|
A remote attacker could entice a user or automated system to unpack a
|
||
|
|
compressed archive with a specially crafted file name, leading to the
|
||
|
|
execution of shell commands from within the filename. That code will be
|
||
|
|
executed with the privileges of the user running unp.
|
||
|
|

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

All unp users should upgrade to the latest version:
