[GLSA-200511-06] fetchmail: Password exposure in fetchmailconf Vulnerability Scan
Vulnerability Scan Summary
fetchmail: Password exposure in fetchmailconf
Detailed Explanation for this Vulnerability Test
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.
A local attacker could exploit the race condition to retrieve
sensitive information like IMAP/POP passwords.
Run "umask 077" to temporarily strengthen default permissions,
then run "fetchmailconf" from the same shell.
All fetchmail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/fetchmail-22.214.171.124-r1"
Threat Level: Medium
