Detail
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. |
