Vulnerability Note VU#484011
Solaris Line Printer Daemon (in.lpd) vulnerable to buffer overflow via transfer job routine
A buffer overflow exists in the Solaris line printer daemon (in.lpd) that may allow a remote intruder to execute arbitrary code with the privileges of the running in.lpd. This daemon runs with root privileges by default on all recent versions of Solaris.
The Solaris in.lpd provides services for remote users to interact with a local printer, listening for remote requests on port 515/tcp. There is an unchecked buffer in the part of the code responsible for transferring print jobs from one machine to another. If given too many jobs to work on at once, an attacker can either crash the printer daemon or attempt to execute arbitrary code with super user privileges on the victim system.
Solaris 2.6 x86
Solaris 7 x86
Solaris 8 x86
A remote intruder may be able to execute arbitrary code with the privileges in the running daemon (typically root). In addition, a remote intruder may be able to crash vulnerable printer daemons.
