Descriptions
The iCalendar component in gwwww1.dll in GroupWise Internet Agent (GWIA) in Novell GroupWise 8.0 before Support Pack 3 allows remote attackers to cause a denial of service (out-of-bounds read and daemon crash) via a crafted date-time string in a .ics attachment.
El componente iCalendar en gwwww1.dll en GroupWise Internet Agent (GWIA) en Novell GroupWise v8.0 anterior al Support Pack 3, permite a atacantes remotos provocar una denegación de servicio (lectura de memoria fuera de rango o caída de aplicación) a través de una cadena de tiempo (fecha y hora) en un adjunto .ics.
Secunia Research has discovered a vulnerability in Novell GroupWise, which can be exploited by malicious people to cause a DoS (Denial of Service). However, no checks are performed by a function in iCalendar to ensure that the supplied date-time string is longer than 8 characters. This may result in an out-of-bounds read access violation, causing GWIA to crash in case a shorter date-time string was supplied via e.g. an e-mail with a specially crafted .ics attachment. Novell GroupWise version 8.0.2 HP3 is affected.
