Anauthenticated, remote user could send a specially-crafted response thatwould cause an smbd child process to enter an infinite loop. Anauthenticated, remote user could use this flaw to exhaust system resources by opening multiple CIFS sessions. (CVE-2009-2906)An uninitialized data access flaw was discovered in the smbd daemon whenusing the non-default "dos filemode" configuration option in "smb.conf". An authenticated, remote user with write access to a file could possibly use this flaw to change an access control list for that file, even when such access should have been denied. (CVE-2009-1888)A flaw was discovered in the way Samba handled users without a homedirectory set in the back-end password database (e.g. "/etc/passwd"). If a share for the home directory of such a user was created (e.g. using the automated "[homes]" share), any user able to access that share could see the whole file system, possibly bypassing intended access restrictions.(CVE-2009-2813)The mount.cifs program printed CIFS passwords as part of its debug output when running in verbose mode. When mount.cifs had the setuid bit set, a local, unprivileged user could use this flaw to disclose passwords from a file that would otherwise be inaccessible to that user. Note: mount.cifs from the samba packages distributed by Red Hat does not have the setuid bit set. This flaw only affected systems where the setuid bit was manually set by an administrator. (CVE-2009-2948)This update also fixes the following bug for SL3:* an earlier update added code to escape input passed to scriptsthat are run by Samba. This code was missing "c" from the list of validcharacters, causing it to be escaped. With this update, the previous patch has been updated to include "c" in the list of valid characters.(BZ#242754)After installing this update, the smb service will be restarted automatically.SL 3.0.x SRPMS:samba-3.0.9-1.3E.16.src.rpm i386:samba-3.0.9-1.3E.16.i386.rpmsamba-client-3.0.9-1.3E.16.i386.rpmsamba-common-3.0.9-1.3E.16.i386.rpmsamba-swat-3.0.9-1.3E.16.i386.rpm x86_64:samba-3.0.9-1.3E.16.i386.rpmsamba-3.0.9-1.3E.16.x86_64.rpmsamba-client-3.0.9-1.3E.16.x86_64.rpmsamba-common-3.0.9-1.3E.16.i386.rpmsamba-common-3.0.9-1.3E.16.x86_64.rpmsamba-swat-3.0.9-1.3E.16.x86_64.rpmSL 4.x SRPMS:samba-3.0.33-0.18.el4_8.src.rpm i386:samba-3.0.33-0.18.el4_8.i386.rpmsamba-client-3.0.33-0.18.el4_8.i386.rpmsamba-common-3.0.33-0.18.el4_8.i386.rpmsamba-swat-3.0.33-0.18.el4_8.i386.rpm x86_64:samba-3.0.33-0.18.el4_8.x86_64.rpmsamba-client-3.0.33-0.18.el4_8.x86_64.rpmsamba-common-3.0.33-0.18.el4_8.i386.rpmsamba-common-3.0.33-0.18.el4_8.x86_64.rpmsamba-swat-3.0.33-0.18.el4_8.x86_64.rpmSL 5.x SRPMS:samba-3.0.33-3.15.el5_4.src.rpm i386:samba-3.0.33-3.15.el5_4.i386.rpmsamba-client-3.0.33-3.15.el5_4.i386.rpmsamba-common-3.0.33-3.15.el5_4.i386.rpmsamba-swat-3.0.33-3.15.el5_4.i386.rpm x86_64:samba-3.0.33-3.15.el5_4.x86_64.rpmsamba-client-3.0.33-3.15.el5_4.x86_64.rpmsamba-common-3.0.33-3.15.el5_4.i386.rpmsamba-common-3.0.33-3.15.el5_4.x86_64.rpmsamba-swat-3.0.33-3.15.el5_4.x86_64.rpm-Connie Sieh-Troy Dawson
