Debian DLA-3354-1 : kopanocore - LTS security update

critical Nessus Plugin ID 172141


The remote Debian host is missing one or more security-related updates.


The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3354 advisory.

- 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.


Upgrade the kopanocore packages.

For Debian 10 buster, these problems have been fixed in version 8.7.0-3+deb10u1.
