Gentoo Linux Security Advisory

Title: wv library: Multiple integer overflows (GLSA 200612-01)
Severity: normal
Exploitable: remote
Date: December 07, 2006
Bug(s): #153800
ID: 200612-01

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: app-text/wv
Vulnerable: < 1.2.3-r1
Unaffected: >= 1.2.3-r1
Architectures: All supported architectures


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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/wv-1.2.3-r1"


References

CVE-2006-4513
