Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Mail Notification 4.0, when WITH_SSL is set to 0 at compile time, uses unencrypted connections for accounts configured with SSL/TLS, which allows remote attackers to obtain sensitive information by sniffing the network.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Mail Notification 4.0, when compiled without SSL support (WITH_SSL=0), fails to properly enforce SSL/TLS for accounts configured to use SSL/TLS and instead falls back to unencrypted connections, allowing sensitive credentials and email content to be intercepted via network sniffing.

MitigationRecompile Mail Notification with SSL support enabled (WITH_SSL=1 or equivalent) and verify that all accounts configured for SSL/TLS are actually using encrypted connections.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Mail Notification version
    Run 'mail-notification --version' or check the installed package version using your system's package manager (e.g., dpkg -l, rpm -qi)
    Affected if The installed version is 4.0
  2. Check SSL compilation flag
    Examine how Mail Notification was compiled. Check for a WITH_SSL flag or SSL-related symbols in the binary using 'strings' or 'nm', or look for SSL libraries linked with the binary using 'ldd' on Linux. Alternatively, check build logs or configuration files from the compilation process.
    Affected if The binary was compiled with WITH_SSL=0 or does not link to SSL libraries (libssl, gnutls)
  3. Review configured accounts for SSL/TLS settings
    Open Mail Notification configuration and examine each configured email account. Look for SSL/TLS, STARTTLS, or encrypted connection options in the account settings.
    Affected if Any account is configured to use SSL/TLS for secure connections
  4. Verify actual connection encryption
    Monitor network traffic from the Mail Notification process using a packet sniffer like tcpdump or Wireshark, or examine connection logs to determine if connections to mail servers are actually encrypted.
    Affected if Accounts configured for SSL/TLS are communicating over unencrypted plaintext connections (typically port 110, 143 instead of 995, 993)

You are affected if Mail Notification 4.0 is installed AND it was compiled without SSL support (WITH_SSL=0) AND you have accounts configured to use SSL/TLS, because the software will silently fall back to unencrypted connections.
