Sun announces the release of patches for Solaris(tm) 8, 7, and
2.6 (SunOS(tm) 5.8, 5.7, and 5.6) which relate to an in.lpd
vulnerability reported in CERT CA-2001-15.
Sun recommends that you install the patches listed in section 4
immediately on systems running SunOS 5.8, 5.7, and 5.6 which
use in.lpd.
2. Who is Affected
Vulnerable: SunOS 5.8, 5.8_x86, 5.7, 5.7_x86, 5.6,
5.6_x86
3. Understanding the Vulnerability
The in.lpd daemon is the BSD print protocol daemon. The in.lpd
daemon implements the network listening service for the BSD
print protocol specified in RFC 1179. The BSD print protocol
provides a remote interface for systems to interact with a
local spooling system. CERT Advisory CA-2001-15 describes a
buffer overflow in the in.lpd daemon which may crash in.lpd or
allow arbitrary code to be executed with elevated privileges
on the victim system. The issue was discovered by ISS X-Force
who published an advisory at:
http://xforce.iss.net/alerts/advise80.php
CERT Advisory CA-2001-15 is available from:
