Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-2724 medium priority: Ubuntu including 2 source packages (cifs-utils, samba), 14 status rows across 7 suites (dapper, hardy, karmic, lucid, maverick, natty, upstream): DNE 4, not-affected 3, released 3, ignored 2, needs-triage 2.
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.
