GLSA 200509-02: Gnumeric: Heap overflow in the included PCRE library

http://security.gentoo.org/

Severity:	normal
Title:	Gnumeric: Heap overflow in the included PCRE library
Date:	09/03/2005
Bugs:	#104010
ID:	200509-02

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	Architecture(s)
app-office/gnumeric	< 1.4.3-r2	>= 1.4.3-r2	All supported architectures

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"
