    CVE-2021-31855

    Summary: Updated messagelib packages fix security vulnerability

    Details: 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. This is not easily noticeable by the user because KMail does not display the decrypted content. With a specially 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 (CVE-2021-31855).
