2.1

Low

Base vector

AV:L/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions ncpfs version 2.2.6

Description The issue is related to the ncpmount, ncpumount, and ncplogin programs in ncpfs. These programs do not properly create lock files, allowing local users to cause a denial of service via unspecified vectors. This can trigger the creation of a /etc/mtab~ file that persists after the program exits.

Recommendations For ncpfs version 2.2.6, consider implementing proper lock file creation mechanisms to prevent the denial of service issue. As a temporary workaround, restrict access to the ncpmount, ncpumount, and ncplogin programs to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
