Package : ecryptfs-utils Vulnerability : multiple Problem type : local Debian-specific: no CVE ID : CVE-2011-1831 CVE-2011-1832 CVE-2011-1834 CVE-2011-1835 CVE-2011-1837 CVE-2011-3145
Several problems have been discovered in ecryptfs-utils, a cryptographic filesystem for Linux.
CVE-2011-1831
Vasiliy Kulikov of Openwall and Dan Rosenberg discovered that eCryptfs incorrectly validated permissions on the requested mountpoint. A local attacker could use this flaw to mount to arbitrary locations, leading to privilege escalation.
CVE-2011-1832
Vasiliy Kulikov of Openwall and Dan Rosenberg discovered that eCryptfs incorrectly validated permissions on the requested mountpoint. A local attacker could use this flaw to unmount to arbitrary locations, leading to a denial of service.
CVE-2011-1834
Dan Rosenberg and Marc Deslauriers discovered that eCryptfs incorrectly handled modifications to the mtab file when an error occurs. A local attacker could use this flaw to corrupt the mtab file, and possibly unmount arbitrary locations, leading to a denial of service.
CVE-2011-1835
Marc Deslauriers discovered that eCryptfs incorrectly handled keys when setting up an encrypted private directory. A local attacker could use this flaw to manipulate keys during creation of a new user.
CVE-2011-1837
Vasiliy Kulikov of Openwall discovered that eCryptfs incorrectly handled lock counters. A local attacker could use this flaw to possibly overwrite arbitrary files.
We acknowledge the work of the Ubuntu distribution in preparing patches suitable for near-direct inclusion in the Debian package.
For the oldstable distribution (lenny), these problems have been fixed in version 68-1+lenny1.
For the stable distribution (squeeze), these problems have been fixed in version 83-4+squeeze1.
For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 95-1.
We recommend that you upgrade your ecryptfs-utils packages.
