Hello oss-security,
just a quick note that offlineimap 8.0.3 fixes CVE-2020-37248
"STARTTLS stripping":
OfflineIMAP before 8.0.3 trusts the server with their STARTTLS
capability prior to authentication, which allows STRIPTLS/man-in-the-
middle attacks, taking over the connection and extracting account
credentials in cleartext.
The key fix commit is…
https://github.com/OfflineIMAP/offlineimap3/commit/46505c53ef995455d66c685f9ec3ff6ea93dbb74
…and issues…
- https://github.com/OfflineIMAP/offlineimap3/issues/222
- https://github.com/OfflineIMAP/offlineimap/issues/669
…are related. The issue was first reported in 2020, hence CVE-2020-*.
