<title>Gnumeric: User-assisted execution of arbitrary code</title>
Several integer overflow vulnerabilities have been reported in Gnumeric,
possibly resulting in user-assisted execution of arbitrary code.
<product type="ebuild">gnumeric</product>
<announced>February 12, 2008</announced>
<revised>February 12, 2008: 01</revised>
<package name="app-office/gnumeric" auto="yes" arch="*">
<unaffected range="ge">1.8.1</unaffected>
<vulnerable range="lt">1.8.1</vulnerable>
The Gnumeric spreadsheet is a versatile application developed as part
of the GNOME Office project.
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 type="normal">
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.
There is no known workaround at this time.
All Gnumeric users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-office/gnumeric-1.8.1&quot;</code>
