SECUNIA ADVISORY ID:
SA35631
VERIFY ADVISORY:
http://secunia.com/advisories/35631/
DESCRIPTION:
NetBSD has acknowledged some vulnerabilities in hack, which can be
exploited by malicious, local users to gain escalated privileges.
1) A boundary error within the "gethdate()" function when processing
the "PATH" environment variable can be exploited to cause a buffer
overflow.
2) A boundary error within the "main()" function when processing the
"GENOCIDED" environment variable in wizard mode can be exploited to
cause a buffer overflow.
Successful exploitation may allow the execution of arbitrary code
with the privileges of the "games" group.
SOLUTION:
Fixed in the CVS repository. See vendor advisory for details.
PROVIDED AND/OR DISCOVERED BY:
NetBSD credits David A. Holland.
