GLSA-200409-27 : glFTPd: Local buffer overflow vulnerability
Medium Nessus Plugin ID 14790
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
There is no known workaround at this time.
SolutionAll glFTPd users should upgrade to the latest version:
# emerge sync # emerge -pv '>=net-ftp/glftpd-1.32-r1' # emerge '>=net-ftp/glftpd-1.32-r1'
