Stack buffer overflow vulnerability in Lotus Domino iCalendar functionality
MWR InfoSecurity and TippingPoint's Zero Day Initiative (ZDI) contacted IBM Lotus to report a potential buffer overflow vulnerability with the Lotus Domino iCalendar functionality.
It is possible to cause a buffer overflow situation based on the iCalendar content included in a calendar invitation.
To exploit this vulnerability, an attacker would have to send an iCalendar invitation with specific parameters. The vulnerability is exposed when the Domino server goes to process that content which could result in remote execution of code.
