Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
