ID:	200802-05

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	Architecture(s)
app-office/gnumeric	< 1.8.1	>= 1.8.1	All supported architectures

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"
