GLSA-200409-32 : getmail: Filesystem overwrite vulnerability

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-200409-32
(getmail: Filesystem overwrite vulnerability)

David Watson discovered a vulnerability in getmail when it is
configured to run as root and deliver mail to the maildirs/mbox files
of untrusted local users. A malicious local user can then exploit a
race condition, or a similar symlink attack, and potentially cause
getmail to create or overwrite files in any directory on the system.

Impact :

An untrusted local user could potentially create or overwrite files in
any directory on the system. This vulnerability may also be exploited
to have arbitrary commands executed as root.

Workaround :

Do not run getmail as a privileged user
or, in version 4, use an
external MDA with explicitly configured user and group privileges.

Solution :

All getmail users should upgrade to the latest version:
# emerge sync
# emerge -pv '>=net-mail/getmail-4.2.0'
# emerge '>=net-mail/getmail-4.2.0'

Risk factor :
