kopano-ical (formerly zarafa-ical) in Kopano Groupware Core through 8.7.16, 9.x through 9.1.0, 10.x through 10.0.7, and 11.x through 11.0.1 and Zarafa 6.30.x through 7.2.x allows memory exhaustion via long HTTP headers.
Zarafa WebAccess 7.1.10 and WebApp 1.6 beta uses weak permissions (644) for config.php, which allows local users to obtain sensitive information by reading the PHP session files. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-0103.
Zarafa 5.00 uses world-readable permissions for the files in the log directory, which allows local users to obtain sensitive information by reading the log files.
WebAccess in Zarafa before 7.1.10 and WebApp before 1.6 stores credentials in cleartext, which allows local Apache users to obtain sensitive information by reading the PHP session files.
The ValidateUserLogon function in provider/libserver/ECSession.cpp in Zarafa 5.00 before 7.1.8 beta2 allows remote attackers to cause a denial of service (crash) via vectors related to "a NULL pointer of the username."
The ValidateUserLogon function in provider/libserver/ECSession.cpp in Zarafa 7.1.8, 6.20.0, and earlier, when using certain build conditions, allows remote attackers to cause a denial of service (crash) via vectors related to "a NULL pointer of the password."
