  - HrAddFBBlock in libfreebusy/freebusyutil.cpp in Kopano Groupware Core before 8.7.7 allows out-of-bounds
    access, as demonstrated by mishandling of an array copy during parsing of ICal data. (CVE-2019-19907)

  - An issue in provider/libserver/ECKrbAuth.cpp of Kopano-Core v11.0.2.51 contains an issue which allows
    attackers to authenticate even if the user account or password is expired. (CVE-2022-26562)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
