Title: glFTPd: Local buffer overflow vulnerability (GLSA 200409-27)
Date: September 21, 2004
glFTPd is vulnerable to a local buffer overflow which may allow arbitrary
glFTPd is a highly configurable FTP server with many features.
Vulnerable: < 1.32-r1
Unaffected: >= 1.32-r1
Architectures: All supported architectures
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.
All 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"
