GNU Screen Braille Module Buffer Overflow Vulnerability
Screen is a freely available, open source terminal management software package. It is distributed and maintained by the Free Software Foundation. It is available for the Unix and Linux platforms. Under some circumstances, it may be possible for a local user to take advantage of a buffer overflow in screen. Due to insufficient bounds checking performed by the braille module of screen, it is possible for a local user to pass long strings of data to the screen program, which could result in an overflow, and the overwriting of process memory. This could result in the execution of arbitrary code. |
