Published: 22 June 2020

In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a workaround, one can disable bitmap cache with -bitmap-cache (default). This is fixed in version 2.1.2.

Notes

AuthorNote
mdeslaur
The freerdp package in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS
does not build a server library. This is simply a client
denial of service that has a negligible security impact.
