BDash 0.31 Buffer Overflow Vulnerability

A vulnerability exists in the game B-DASH v0.31, distributed with old versions of Linux and certain non-current versions of Slackware.

Due to incorrect handling of the $HOME environment variable in calls to the vconfig() function, it is possible for users to overwrite stack variables such as the calling function's return address with arbitrary values that can alter the program's flow of execution.

If exploited, the user can at the very least cause the host to crash. More advanced attacks can result in arbitrary code execution on the victim host.
