559579: CVE-2010-0296 glibc: Improper encoding of names with certain special character in utilities for writing to mtab table

The MITRE CVE dictionary describes this issue as:

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.
