Buffer overflow in GNU Chess (gnuchess) 5.02 and earlier, if modified or used in a networked capacity contrary to its own design as a single-user application, may allow local or remote attackers to execute arbitrary code via a long command.

gnuchess: Stack-based buffer overflow on user move input

Stack-based buffer overflow in the ValidateMove function in frontend/move.cc in GNU Chess (aka gnuchess) before 6.2.4 might allow context-dependent attackers to execute arbitrary code via a large input, as demonstrated when in UCI mode.

gnuchess: buffer overflows in the cmd_pgnload() and cmd_pgnreplay() functions in frontend/cmd.cc

GNU Chess 6.2.7 allows attackers to execute arbitrary code via crafted PGN (Portable Game Notation) data. This is related to a buffer overflow in the use of a .tmp.epd temporary file in the cmd_pgnload and cmd_pgnreplay functions in frontend/cmd.cc.

gnuchess: stack-based overflow in cmd_load in frontend/cmd.cc via crafted EPD file

In GNU Chess 6.2.5, there is a stack-based buffer overflow in the cmd_load function in frontend/cmd.cc via a crafted chess position in an EPD file.
