Synopsis
========
Gnumeric is vulnerable to a heap overflow, possibly leading to the
execution of arbitrary code.
Background
==========
The Gnumeric spreadsheet is a versatile application developed as part
of the GNOME Office project. libpcre is a library providing functions
for Perl-compatible regular expressions.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/gnumeric < 1.4.3-r2 >= 1.4.3-r2
Description
===========
Gnumeric contains a private copy of libpcre which is subject to an
integer overflow leading to a heap overflow (see GLSA 200508-17).
Impact
======
An attacker could potentially exploit this vulnerability by tricking a
user into opening a specially crafted spreadsheet, which could lead to
the execution of arbitrary code with the privileges of the user running
Gnumeric.
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-1.4.3-r2"
