|
This exploit abuses an unpublished vulnerability in the
|
|
|
|
HP-UX LPD service. This flaw allows an unauthenticated
|
|
|
|
attacker to execute arbitrary commands with the privileges
|
|
|
|
of the root user. The LPD service is only exploitable when
|
|
|
|
the address of the attacking system can be resolved by the
|
|
|
|
target. This vulnerability was silently patched with the
|
|
|
|
buffer overflow flaws addressed in HP Security Bulletin
|
|
|
|
HPSBUX0208-213.
