Evolution iCalendar buffer overflow

evolution-icalendar-bo (42824) The risk level is classified as HighHigh Risk

Description:

Evolution is vulnerable to a buffer overflow, caused by improper bounds checking by iCalendar. By persuading a victim to open a specially-crafted iCalendar attachment containing an overly long timezone string when the ITip Formatter plugin is disabled, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
