GLSA-200511-06 : fetchmail: Password exposure in fetchmailconf

low Nessus Plugin ID 20156

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200511-06 (fetchmail: Password exposure in fetchmailconf)

 Thomas Wolff discovered that fetchmailconf opens the configuration file with default permissions, writes the configuration to it, and only then restricts read permissions to the owner.
 Impact :

 A local attacker could exploit the race condition to retrieve sensitive information like IMAP/POP passwords.
 Workaround :

 Run 'umask 077' to temporarily strengthen default permissions, then run 'fetchmailconf' from the same shell.

Solution

All fetchmail users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/fetchmail-6.2.5.2-r1'
