Vulnerability Assessment Details

[GLSA-200412-09] ncpfs: Buffer overflow in ncplogin and ncpmap

Vulnerability Assessment Summary
ncpfs: Buffer overflow in ncplogin and ncpmap

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200412-09
(ncpfs: Buffer overflow in ncplogin and ncpmap)


Karol Wiesek discovered a buffer overflow in the handling of the
'-T' option in the ncplogin and ncpmap utilities, which are both
installed as SUID root by default.

Impact

A local attacker could trigger the buffer overflow by calling one
of these utilities with a carefully crafted command line, potentially
resulting in execution of arbitrary code with root rights.

Workaround

There is no known workaround at this time.
