Summary
Red Hat Security Advisory: : Updated SANE packages fix remote vulnerabilities

Notes

Topic
Updated SANE packages that resolve a number of vulnerabilities with the saned daemon are now available.
Details
SANE is a package for using document scanners. 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. Additionally, the updated packages for Red Hat Linux 8.0 include a fix for a bug that could cause hardware damage to Epson 1260 scanners. Releases prior to Red Hat Linux 8.0 are unaffected by this issue. Red Hat Linux 9 is affected by this, but will be covered by a separate advisory. Users of SANE (particularly those that use saned for remote scanner access) should upgrade to these errata packages, which resolve these issues.
