Description Stefan Cornelius 2012-06-15 08:52:05 UTC

A denial of service flaw was found in the way VTE, a terminal emulator
widget, processed certain escape sequences with large repeat counts.
A remote attacker could provide a specially-crafted file, which once
opened in a terminal using the VTE terminal emulator could lead to
excessive CPU consumption.
