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.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.
