NVD Description
Note: Versions mentioned in the description apply only to the upstream guacamole-client package and not the guacamole-client package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
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.
