Application: less 394 and prior
Type: Format strings vulnerability

There exists a format strings bug in the less application present in
most flavors of UNIX.  It could be leveraged for privilege escalation
if the calling application is setuid/setgid and does not properly drop
privileges.

$ export LESSOPEN=%s%n
$ less somefile
Segmentation fault
$
