  "details" : [ "The UDF filesystem implementation in the Linux kernel before 3.18.2 does not ensure that space is available for storing a symlink target's name along with a trailing \\0 character, which allows local users to obtain sensitive information via a crafted filesystem image, related to fs/udf/symlink.c and fs/udf/unicode.c.", "A path length checking flaw was found in Linux kernels built with UDF file system (CONFIG_UDF_FS) support. An attacker able to mount a corrupted/malicious UDF file system image could use this flaw to leak kernel memory to user-space." ],
