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.
Created freerdp tracking bugs for this issue:
Affects: epel-all [bug 1854915]
Affects: fedora-all [bug 1854913]
This flaw affects freerdp clients and servers. In winpr/libwinpr/sspi/NTLM/ntlm_av_pairs.c, there is a static array AV_PAIR_STRINGS which could be indexed out-of-bounds by routines in the file. The patch uses a getter and sanitization routine to prevent this and modifies the calling functions appropriately.
