Описание
In FreeRDP less than or equal to 2.0.0, a possible resource exhaustion vulnerability can be performed. Malicious clients could trigger out of bound reads causing memory allocation with random size. This has been fixed in 2.1.0.

Описание
In FreeRDP less than or equal to 2.0.0, when running with logger set to "WLOG_TRACE", a possible crash of application could occur due to a read of an invalid array index. Data could be printed as string to local terminal. This has been fixed in 2.1.0.

- CVE-2020-11019
- SUSE Bug 1171441
Описание
In FreeRDP less than or equal to 2.0.0, an Integer Overflow to Buffer Overflow exists. When using /video redirection, a manipulated server can instruct the client to allocate a buffer with a smaller size than requested due to an integer overflow in size calculation. With later messages, the server can manipulate the client to write data out of bound to the previously allocated buffer. This has been patched in 2.1.0.

Описание
In FreeRDP less than or equal to 2.0.0, an outside controlled array index is used unchecked for data used as configuration for sound backend (alsa, oss, pulse, ...). The most likely outcome is a crash of the client instance followed by no or distorted sound or a session disconnect. If a user cannot upgrade to the patched version, a workaround is to disable sound for the session. This has been patched in 2.1.0.
