Severity: normal
Exploitable: remote
Date: September 03, 2005
Bug(s): #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: app-office/gnumeric
Vulnerable: < 1.4.3-r2
Unaffected: >= 1.4.3-r2
Architectures: All supported architectures

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:
