CVE-2021-31855
https://notcve.org/view.php?id=CVE-2021-31855
KDE Messagelib through 5.17.0 reveals cleartext of encrypted messages in some situations. Deleting an attachment of a decrypted encrypted message stored on a remote server (e.g., an IMAP server) causes KMail to upload the decrypted content of the message to the remote server. With a crafted message, a user could be tricked into decrypting an encrypted message and then deleting an attachment attached to this message. If the attacker has access to the messages stored on the email server, then the attacker could read the decrypted content of the encrypted message. This occurs in ViewerPrivate::deleteAttachment in messageviewer/src/viewer/viewer_p.cpp. • https://github.com/KDE/messagelib/commit/3b5b171e91ce78b966c98b1292a1bcbc8d984799 https://kde.org/info/security/advisory-20210429-1.txt • CWE-312: Cleartext Storage of Sensitive Information •

https://notcve.org/view.php?id=CVE-2017-9604
KDE kmail before 5.5.2 and messagelib before 5.5.2, as distributed in KDE Applications before 17.04.2, do not ensure that a plugin's sign/encrypt action occurs during use of the Send Later feature, which allows remote attackers to obtain sensitive information by sniffing the network. KDE kmail anterior a la 5.5.2 y messagelib anterior a la 5.5.2, como distribuciones en aplicaciones KDE anteriores a la 17.04.2, no asegura que la acción de firma del plugin ocurre durante el uso de la característica Send Later, lo que permite a un atacante remoto obtener información sensible mediante la observación de la red. • https://commits.kde.org/kmail/78c5552be2f00a4ac25bd77ca39386522fca70a8 https://commits.kde.org/messagelib/c54706e990bbd6498e7b1597ec7900bc809e8197 • CWE-311: Missing Encryption of Sensitive Data •
