Ncpfs : Security Vulnerabilities, CVEs, Published In 2010

ncpfs 2.2.6 allows local users to cause a denial of service, obtain sensitive information, or possibly gain privileges via symlink attacks involving the (1) ncpmount and (2) ncpumount programs.

sutil/ncpumount.c in ncpumount in ncpfs 2.2.6 produces certain detailed error messages about the results of privileged file-access attempts, which allows local users to determine the existence of arbitrary files via the mountpoint name.

The (1) ncpmount, (2) ncpumount, and (3) ncplogin programs in ncpfs 2.2.6 do not properly create lock files, which allows local users to cause a denial of service (application failure) via unspecified vectors that trigger the creation of a /etc/mtab~ file that persists after the program exits.
