CVE-2020-15953 (GCVE-0-2020-15953)

Vulnerability from cvelistv5 – Published: 2020-07-27 06:07 – Updated: 2024-08-04 13:30

Summary

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."
