Synopsis :

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

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-'

Risk factor :

Low / CVSS Base Score : 2.1
