Description:
Steve Kemp has reported multiple vulnerabilities in Linley's Dungeon Crawl, which potentially can be exploited by malicious, local users to gain escalated privileges.
The vulnerabilities are caused due to boundary errors when handling environment variables. These can be exploited to cause buffer overflows by supplying an overly long, specially crafted strings in an environment variable.
Successful exploitation may potentially allow execution of arbitrary code on systems where the game has been installed setuid or setgid.
Solution:
If this is considered a security issue, remove the game from the system or remove any suid or sgid bits.
Games should never be installed on production systems.
