Synopsis ========
A vulnerability in Roundcube could potentially lead to arbitrary code execution.
Background ==========
Free and open source webmail software for the masses, written in PHP.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/roundcube < 1.2.3 >= 1.2.3
Description ===========
Roundcube, when no SMTP server is configured and the sendmail program is enabled, does not properly restrict the use of custom envelope-from addresses on the sendmail command line.
Impact ======
An authenticated remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
Workaround ==========
Don't use a MTA (Mail Transfer Agent) in conjunction with Roundcube which implements sendmail's "-O" or "-X" parameter, or configure Roundcube to use a SMTP server as recommended by upstream.
Resolution ==========
All Roundcube users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/roundcube-1.2.3"
References ==========
