[GLSA-200409-27] glFTPd: Local buffer overflow vulnerability Vulnerability Scan
Vulnerability Scan Summary
glFTPd: Local buffer overflow vulnerability
Detailed Explanation for this Vulnerability Test
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 allow 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.
