Description Jan Lieskovsky 2011-06-09 15:27:55 UTC 
An memory exhaustion flaw was found in the way VTE, a terminal emulator
widget, processed certain character sequences. A remote attacker could
provide a specially-crafted file, which once opened in a terminal using
the VTE terminal emulator could lead to excessive memory and CPU consumption.
