Isaac Wilcox has discovered numerous means of plain-text password disclosure due to errors in secure connection establishment.

SMTP and LMTP delivery modes are not affected by this vulnerability. An attacker could also perform a Man-in-the-Middle attack, and obtain plain-text authentication credentials of users connecting to a Fetchmail process.
Workaround :
There is no known workaround at this time.
Solution
All fetchmail users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/fetchmail-6.3.6'
