Ubuntu Security Notice USN-871-2
10th December, 2009
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 9.10
- Ubuntu 9.04
- Ubuntu 8.10
USN-871-1 fixed vulnerabilities in KDE. This update provides the
corresponding updates for KDE 4.
This update also fixes a directory traversal flaw in KDE when processing
help:// URLs. This issue only affected Ubuntu 8.10.
Original advisory details:
It was discovered that the KDE libraries could use KHTML to process an
unknown MIME type. If a user or application linked against kdelibs were
tricked into opening a crafted file, an attacker could potentially trigger
XMLHTTPRequests to remote sites.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 9.10:
- kdelibs5 4:4.3.2-0ubuntu7.2
- Ubuntu 9.04:
- kdelibs5 4:4.2.2-0ubuntu5.4
- Ubuntu 8.10:
- kdelibs5 4:4.1.4-0ubuntu1~intrepid1.5
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart your session to effect
the necessary changes.
