Bug 208356 (CVE-2008-0668) – app-office/gnumeric < 1.8.1 excel_read_HLINK XLS opcodes code excution (CVE-2008-0668)

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Pierre-Yves Rofes (RETIRED) 2008-01-31 21:49:00 UTC]

A vulnerability has been reported in Gnumeric, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to integer overflows and signedness errors when processing XLS HLINK opcodes within the "excel_read_HLINK()" function in plugins/excel/ms-excel-read.c. This can be exploited to corrupt the stack via a specially crafted XLS file.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 1.6.3. Versions prior to 1.8.1 may also be affected.

Solution:
Update to version 1.8.1.

Gnome-office, is 1.8.1 ready for going stable? please advise. 

[Comment 2 Gilles Dartiguelongue (RETIRED) 2008-01-31 22:13:08 UTC]

it's a bugfix only release following 1.8.0 so I'd say yes. Plus it has no currently opened bug against it in gentoo.

[Comment 3 Robert Buchholz (RETIRED) 2008-02-01 22:23:11 UTC]

Arches, please test and mark stable:
=app-office/gnumeric-1.8.1
Target keywords : "alpha amd64 hppa ia64 ppc ppc64 release sparc x86"

[Comment 4 Markus Meier 2008-02-02 02:20:04 UTC]

x86 stable. Please note:
dodoc: TODO does not exist
