==========================================================
Ubuntu Security Notice USN-18-1 November 05, 2004
zip vulnerability
CAN-2004-1010
==========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

zip

The problem can be corrected by upgrading the affected package to version 2.30-6ubuntu0.1. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

HexView discovered a buffer overflow in the zip package. The overflow is triggered by creating a ZIP archive of files with very long path names. This vulnerability might result in execution of arbitrary code with the privileges of the user who calls zip.

This flaw may lead to privilege escalation on systems which automatically create ZIP archives of user supplied files, like backup systems or web applications.
