A race condition in Guacamole's terminal emulator in versions 0.9.5 through 0.9.10-incubating could allow writes of blocks of printed data to overlap. Such overlapping writes could cause packet data to be misread as the packet length, resulting in the remaining data being written beyond the end of a statically-allocated buffer.

Affected Packages

Maven org.apache.guacamole:guacamole-common

Affected versions: 0.9.5 (fixed in 0.9.11-incubating)
