Name of the Vulnerable Software and Affected Versions FreeRDP versions 1.1 through 1.9

Description The issue is related to an out-of-bounds read in the autodetect recv bandwidth measure results function. A malicious server can extract up to 8 bytes of client memory with a manipulated message by providing a short input and reading the measurement result data.

Recommendations For versions prior to 2.0.0, update to version 2.0.0 to resolve the issue. As a temporary workaround, consider restricting access to the autodetect recv bandwidth measure results function until a patch is available.
