OpenOffice.org: Heap overflow in included libcurl

Background

OpenOffice.org is an office productivity suite, including word processing, spreadsheet, presentation, data charting, formula editing and file conversion facilities. libcurl, which is included in OpenOffice.org, is a free and easy-to-use client-side library for transferring files with URL syntaxes, supporting numerous protocols.

Description

OpenOffice.org includes libcurl code. This libcurl code is vulnerable to a heap overflow when it tries to parse a URL that exceeds a 256-byte limit (GLSA 200512-09).

Impact

An attacker could entice a user to call a specially crafted URL with OpenOffice.org, potentially resulting in the execution of arbitrary code with the rights of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All OpenOffice.org binary users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.0.2"

All OpenOffice.org users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.0.1-r1"
