PACKAGE : sane
SUMMARY : Vulnerabilities in saned and in temporary files handling

DESCRIPTION
SANE (Scanner Access Now Easy) is an interface to both local and
networked scanners and other image acquisition devices. The sane
package contains several scanner drivers, utilities and saned, a
application that allows the sharing of scanners across a network.
This update fixes several vulnerabilities in the sane package:
- Remote vulnerabilities in saned. These vulnerabilities can be
exploited by remote attackers to cause a denial of service or even
execute arbitrary code with the privileges of the user running saned
(which is usually root). The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned[1,2,3,4,5,6] the names
CAN-2003-0773, CAN-2003-0774, CAN-2003-0775, CAN-2003-0776,
CAN-2003-0777 and CAN-2003-0778 to these issues.
- Temporary file handling vulnerabilities (does not affect Conectiva
Linux 9). In several sane backends (drivers), temporary files are
created in an unsafe manner. A local attacker can exploit these
vulnerabilities to overwrite arbitrary system or user files. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2001-0890[7] to this issue.
The Conectiva Linux 9 package (sane-1.0.9) also includes fixes for a
bug[8] in the plustek driver which may cause hardware damage in EPSON
1260 scanners (previous versions do not contain the driver).
SOLUTION
All users of the sane package should upgrade.
