Ubuntu Security Notice USN-300-1
14th June, 2006
wv2 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
- Ubuntu 5.10
- Ubuntu 5.04
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.06 LTS:
- libwv2-dev 0.2.2-5ubuntu0.1
- libwv2-1c2 0.2.2-5ubuntu0.1
- Ubuntu 5.10:
- libwv2-dev 0.2.2-1ubuntu2.1
- libwv2-1c2 0.2.2-1ubuntu2.1
- Ubuntu 5.04:
- libwv2-dev 0.2.2-1ubuntu1.1
- libwv2-1 0.2.2-1ubuntu1.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart KWord to effect
the necessary changes.
