Severity: Normal Title: unp: Arbitrary command execution Date: January 09, 2008 Bugs: #203106 ID: 200801-01

Synopsis ========
unp allows execution of arbitrary code via malicious file names.
Background ==========
unp is a script for unpacking various file formats.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/unp < 1.0.14 >= 1.0.14
Description ===========
Erich Schubert from Debian discovered that unp does not escape file names properly before passing them to calls of the shell.
Impact ======
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 ==========
There is no known workaround at this time.
Resolution ==========
All unp users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/unp-1.0.14"
