Vulnerability  : buffer overflow
Problem type   : local
Debian-specific: no
CVE ID         : CVE-2006-0224

Johnny Mast discovered a buffer overflow in libast, the library of
assorted spiffy things, that can lead to the execution of arbitary
code.  This library is used by eterm which is installed setgid uid
