Synopsis
========
The wv library is vulnerable to multiple integer overflows which could
lead to the execution of arbitrary code.
Background
==========
wv is a library for conversion of MS Word DOC and RTF files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/wv < 1.2.3-r1 >= 1.2.3-r1
Description
===========
The wv library fails to do proper arithmetic checks in multiple places,
possibly leading to integer overflows.
Impact
======
An attacker could craft a malicious file that, when handled with the wv
library, could lead to the execution of arbitrary code with the
permissions of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All wv library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/wv-1.2.3-r1"
