Synopsis ========
A vulnerability has been discovered in Courier-IMAP allowing for remote code execution with root privileges.
Background ==========
Courier-IMAP is an IMAP server which is part of the Courier mail system. It provides access only to maildirs.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/courier-imap < 4.0.6-r2 >= 4.0.6-r2
Description ===========
CJ Kucera has discovered that some Courier-IMAP scripts don't properly handle the XMAILDIR variable, allowing for shell command injection.
Impact ======
A remote attacker could send specially crafted login credentials to a Courier-IMAP server instance, possibly leading to remote code execution with root privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Courier-IMAP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/courier-imap-4.0.6-r2"
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
