Horde Groupware contains backdoor
Unknown perpetrators infiltrated a backdoor into several installation packages during an attack on groupware provider Horde's FTP server. Horde 3.3.12, Groupware 1.2.10 and the webmail edition of the groupware product are all affected. Horde 4 was not modified. The CVS and Git servers are also unaffected.
