Mercury/32 IMAP server lets logged‑in users run code

CVE-2007-5018 · published 19 years ago
Summary

The IMAP service in Mercury/32 version 4.52 can overflow its memory when a signed‑in user sends an overly long SEARCH command. This can let that user execute their own code on the server, potentially compromising data and other users. Update to a patched version or restrict IMAP access to trusted users while a fix is applied.
