KDE K-mail 1.2

KMail 1.9.5 and earlier does not properly use the --status-fd argument when invoking GnuPG, which prevents KMail from visually distinguishing between signed and unsigned portions of OpenPGP messages with multiple components, which allows remote attackers to forge the contents of a message without detection.

Kmail 1.2 on KDE 2.1.1 allows remote attackers to cause a denial of service (crash) via an email message whose body is approximately 55 K long.
