MGASA-2020-0366 - Updated libetpan packages fix a security vulnerability

Publication date: 15 Sep 2020
URL: https://advisories.mageia.org/MGASA-2020-0366.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-15953

LibEtPan through 1.9.4, as used in MailCore 2 through 0.6.3 and other
products, has a STARTTLS buffering issue that affects IMAP, SMTP, and POP3.
When a server sends a "begin TLS" response, the client reads additional data
(e.g., from a meddler-in-the-middle attacker) and evaluates it in a TLS
context, aka "response injection". (CVE-2020-15953).
