The version of freetype installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-27406 advisory.

  • FreeType commit 22a0cccb4d9d002f33c1ba7a4b36812c7d4f46b5 was discovered to contain a segmentation violation via the function FT_Request_Size. (CVE-2022-27406)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
