Package        : wv2
Vulnerability  : integer overflow
Problem type   : local (remote)
Debian-specific: no
CVE ID         : CVE-2006-2197

A boundary checking error has been discovered in wv2, a library for
accessing Microsoft Word documents, which can lead to an integer
overflow induced by processing word files.

The old stable distribution (woody) does not contain wv2 packages.

For the stable distribution (sarge) this problem has been fixed in
version 0.2.2-1sarge1

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your libwv packages.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given at the end of this advisory:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

Ubuntu Security Notice 300-1 (PacketStormID:F47553)
2006-06-21 00:00:00

Ubuntu Security Notice 300-1 - libwv2 did not sufficiently check the validity of its input. Certain invalid Word documents caused a buffer overflow. By tricking a user into opening a specially crafted Word file with an application that uses libwv2, this could be exploited to execute arbitrary code with the user's privileges.

Ubuntu Security Notice USN-300-1              June 14, 2006
wv2 vulnerability

A security issue affects the following Ubuntu releases:

Ubuntu 5.04
Ubuntu 5.10
Ubuntu 6.06 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 5.04:
  libwv2-1                       0.2.2-1ubuntu1.1
  libwv2-dev                     0.2.2-1ubuntu1.1

Ubuntu 5.10:
  libwv2-1c2                     0.2.2-1ubuntu2.1
  libwv2-dev                     0.2.2-1ubuntu2.1

Ubuntu 6.06 LTS:
  libwv2-1c2                     0.2.2-5ubuntu0.1
  libwv2-dev                     0.2.2-5ubuntu0.1

After a standard system upgrade you need to restart KWord to effect
the necessary changes.

Details follow:

libwv2 did not sufficiently check the validity of its input. Certain
invalid Word documents caused a buffer overflow. By tricking a user
into opening a specially crafted Word file with an application that
uses libwv2, this could be exploited to execute arbitrary code with
the user's privileges.

The only packaged application using this library is KWord.

wvWare wv2 0.2.3

- 漏洞讨论

The wv2 library is prone to a remote buffer-overflow vulnerability. This issue is due to the library's failure to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.

This issue allows remote attackers to execute arbitrary machine code in the context of applications that use the affected library to parse malicious Microsoft Word files.

Version 0.2.2 of the wv2 library is vulnerable to this issue; other versions may also be affected.
