Description

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.

Affected products

GNU C Library (glibc): through 2.11.1; 2.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5 (+32)
