Crashmail 1.6 contains a stack-based buffer overflow vulnerability that allows remote attackers to execute arbitrary code by sending malicious input to the application. Attackers can craft payloads with ROP chains to achieve code execution in the application context, with failed attempts potentially causing denial of service.
