CVE-2016-10727: Canonical Ubuntu Linux

Critical severity, CVSS 9.8. EPSS: 2.9% chance of exploitation in the next 30 days.

camel/providers/imapx/camel-imapx-server.c in the IMAPx component in GNOME evolution-data-server before 3.21.2 proceeds with cleartext data containing a password if the client wishes to use STARTTLS but the server will not use STARTTLS, which makes it easier for remote attackers to obtain sensitive information by sniffing the network. The server code was intended to report an error and not proceed, but the code was written incorrectly.

Affected products

• Canonical Ubuntu Linux: version 14.04 only; version 16.04 only
• Gnome Evolution: before 3.21.2 (fixed in 3.21.2)
