Discussion
Debian GNU/Linux netstd Vulnerabilities
The netstd package, included with the Debian GNU/Linux distribution is vulnerable to two buffer overflow attacks. The first is in the bootp server, the second in the FTP client.
Bootpd version 2.4.3(and earlier) is prone to a number of buffer overflow conditions that may allow a remote attacker to fully compromise a host running a vulnerable version. This is due to improper bounds checking in the handling of the boot file/location specified in a bootp request packet, and in the error
logging facility. This vulnerability is specific to the bootp daemon and any Unix distributions that ship with the affected version should be considered vulnerable.
A buffer overflow condition also exists in the netstd FTP client, which may be exploited by a local attacker to potentially elevate privileges.
