Description Mark J. Cox 2003-09-18 15:01:00 UTC 
Sane includes a daemon program (called saned) that enables a single machine
connected to a scanner to be used remotely. This program contains several
vulnerabilities.

NOTE: Although the SANE packages include this program, it is not used by
default under Red Hat Linux.

The IP address of the remote host is only checked after the first
communication occurs, causing saned.conf restrictions to be ineffective for
the first communication. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0773 to this issue.

A connection that is dropped early causes one of several problems. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the names CAN-2003-0774, CAN-2003-0775, and CAN-2003-0777 to these issues.

Lack of error checking can cause various other unfavorable consequences.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2003-0776 and CAN-2003-0778 to these issues.

Errata in progress.
