Ubuntu Security Notice USN-962-1
15th July, 2010
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
- Ubuntu 9.10
- Ubuntu 9.04
arbitrary command execution via terminal escape codes
- vte - Terminal emulator widget for GTK+ 2.0
Janne Snabb discovered that applications using VTE, such as gnome-terminal,
did not correctly filter window and icon title request escape codes. If a
user were tricked into viewing specially crafted output in their terminal,
a remote attacker could execute arbitrary commands with user privileges.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 10.04 LTS:
- libvte9 1:0.23.5-0ubuntu1.1
- Ubuntu 9.10:
- libvte9 1:0.22.2-0ubuntu2.1
- Ubuntu 9.04:
- libvte9 1:0.20.0-0ubuntu2.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart your session to make
all the necessary changes.
