Description Jan Lieskovsky 2010-03-11 14:24:27 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-0790 to
the following vulnerability:

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.

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-0791 to
the following vulnerability:

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.

These issues affect the versions of the ncpfs package, 
as shipped with Fedora release of 11 and 12.

Please fix.
