CVE-2020-11097

Published: 22 June 2020

In FreeRDP before version 2.1.2, an out of bounds read occurs resulting in accessing a memory location that is outside of the boundaries of the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This is fixed in version 2.1.2.

Notes

AuthorNote
mdeslaur
The freerdp package in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS
