Vulnerability Assessment Details

[GLSA-200409-27] glFTPd: Local buffer overflow vulnerability

Vulnerability Assessment Summary
glFTPd: Local buffer overflow vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200409-27
(glFTPd: Local buffer overflow vulnerability)

The glFTPd server is vulnerable to a buffer overflow in the 'dupescan'
program. This vulnerability is due to an unsafe strcpy() call which can
cause the program to crash when a large argument is passed.

Impact

A local user with malicious intent can pass a parameter to the dupescan
program that exceeds the size of the buffer, causing it to overflow. This
can lead the program to crash, and potentially permit arbitrary code
execution with the permissions of the user running glFTPd, which could be
the root user.

Workaround

There is no known workaround at this time.
