not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
The encode_name macro in misc/mntent_r.c in the GNU C Library (aka glibc or libc6) 2.11.1 and earlier, as used by ncpmount and mount.cifs, does not properly handle newline characters in mountpoint names, which allows local users to cause a denial of service (mtab corruption), or possibly modify mount options and gain privileges, via a crafted mount request.
