Synopsis
========
Several integer overflow vulnerabilities have been reported in
Gnumeric, possibly resulting in user-assisted execution of arbitrary
code.
Background
==========
The Gnumeric spreadsheet is a versatile application developed as part
of the GNOME Office project.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/gnumeric < 1.8.1 >= 1.8.1
Description
===========
Multiple integer overflow and signedness errors have been reported in
the excel_read_HLINK() function in file plugins/excel/ms-excel-read.c
when processing XLS HLINK opcodes.
Impact
======
A remote attacker could entice a user to open a specially crafted XLS
file, possibly resulting in the remote execution of arbitrary code with
the privileges of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Gnumeric users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/gnumeric-1.8.1"
