CVE-2020-11086

Published: 29 May 2020

In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_ntlm_v2_client_challenge that reads up to 28 bytes out-of-bound to an internal structure. This has been fixed in 2.1.0.

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.
