Synopsis
========
zip contains a buffer overflow when creating a ZIP archive of files
with very long path names. This could lead to the execution of
arbitrary code.
Background
==========
zip is a compression and file packaging utility.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/zip <= 2.3-r3 >= 2.3-r4
Description
===========
zip does not check the resulting path length when doing recursive
folder compression.
Impact
======
An attacker could exploit this by enticing another user or web
application to create an archive including a specially-crafted path
name, potentially resulting in the execution of arbitrary code with the
permissions of the user running zip.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All zip users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/zip-2.3-r4"
