Test ID:1.3.6.1.4.1.25623.1.1.10.2021.0208
Category:Mageia Linux Local Security Checks
Title:Mageia: Security Advisory (MGASA-2021-0208)
Summary:The remote host is missing an update for the 'messagelib' package(s) announced via the MGASA-2021-0208 advisory.
Description:Summary:
The remote host is missing an update for the 'messagelib' package(s) announced via the MGASA-2021-0208 advisory.

Vulnerability Insight:
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).

Affected Software/OS:
'messagelib' package(s) on Mageia 7, Mageia 8.

Solution:
Please install the updated package(s).

CVSS Score:
4.0
