FreeRDP vulnerability

What happened

FreeRDP versions before 3.31.0 contain an uninitialized heap memory disclosure vulnerability in the urbdrc USB redirection channel. A malicious RDP server can induce failing USB transfers to read uninitialized heap memory from the client, defeating ASLR and enabling remote code execution when chained with memory corruption vulnerabilities.

Affected versions

FreeRDP: 2.0.0 through before 3.0.0 (semver); 3.0.0 through before 3.31.0 (semver); before 3.31.0 (semver) Fixed: See vendor advisory.
