An issue was discovered in the ROS communications-related packages (aka roscomm or ros-melodic-ros-comm) through 1.14.3. parseOptions() in tools/rosbag/src/record.cpp has an integer overflow when a crafted split option can be entered on the command line.

Integer Overflow or Wraparound vulnerability in the XML RPC library of OpenRobotics roscomm communications packages allows unauthenticated network traffic to cause unexpected behavior. This issue affects: OpenRobotics roscomm communications packages Noetic and prior versions. Fixed in https://github.com/ros/roscomm/pull/2065.

An issue was discovered in the ROS communications-related packages (aka roscomm or ros-melodic-ros-comm) through 1.14.3. A buffer overflow allows attackers to cause a denial of service and possibly execute arbitrary code via an IP address with a long hostname.

An issue was discovered in the ROS communications-related packages (aka roscomm or ros-melodic-ros-comm) through 1.14.3. ROSASSERTMSG only works when ROSASSERTENABLED is defined. This leads to a problem in the remove() function in clients/roscpp/src/libros/spinner.cpp. When ROSASSERTENABLED is not defined, the iterator loop will run out of the scope of the array, and cause denial of service for other components (that depend on the communication-related functions of this package). NOTE: The reporter of this issue now believes it was a false alarm.
