RoundCube Webmail (roundcubemail) before 0.2-beta allows remote attackers to cause a denial of service (memory consumption) via crafted size parameters that are used to create a large quota image.
Cross-site scripting (XSS) vulnerability in RoundCube webmail 0.1rc2, 2007-12-09, and earlier versions, when using Internet Explorer, allows remote attackers to inject arbitrary web script or HTML via style sheets containing expression commands.
roundcube webmail Alpha, with a default high verbose level ($rcmail_config['debug_level'] = 1), allows remote attackers to obtain the full path of the application via an invalid_task parameter, which leaks the path in an error message.
