Thank you for the bug, Daniel. Please choose bug Summaries that are much shorter. ;) I believe this is fixed in =net-fs/cifs-utils-5.1 via commit http://git.samba.org/?p=cifs-utils.git;a=commit;h=1e7a32924b22d1f786b6f490ce8590656f578f91. @samba, would this also affect net-fs/samba and in which versions? CVE-2011-2724 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-2724): The check_mtab function in client/mount.cifs.c in mount.cifs in smbfs in Samba 3.5.10 and earlier does not properly verify that the (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0547. I will include this on the Samba GLSA, but no GLSA will be issued for net-fs/cifs-utils for ~arch only. "Cleaning up vulnerable versions CVE-2011-2724 bug 382263" @samba: In the future it would be nice to update the bug, also, so we don't have this hanging for so many months. This issue was resolved and addressed in GLSA 201206-22 at http://security.gentoo.org/glsa/glsa-201206-22.xml by GLSA coordinator Sean Amoss (ackle). |
