CVE-2020-4030

Published: 22 June 2020

In FreeRDP before version 2.1.2, there is an out of bounds read in TrioParse. Logging might bypass string length checks due to an integer overflow. 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.
