CVE-2020-14929: Alpine Project Alpine

High severity, CVSS 7.5. EPSS: 1.8% chance of exploitation in the next 30 days.

Alpine before 2.23 silently proceeds to use an insecure connection after a /tls is sent in certain circumstances involving PREAUTH, which is a less secure behavior than the alternative of closing the connection and letting the user decide what they would like to do.

Affected products

• Alpine Project Alpine: before 2.23 (fixed in 2.23)
• Debian Debian Linux: version 8.0 only
• Fedoraproject Fedora: version 31 only; version 32 only
