Description:
Paul Szabo has reported some vulnerabilities in the Linux NetKit FTP Server, which can be exploited by malicious, local users to gain knowledge of potentially sensitive information, or perform certain actions with escalated privileges.
1) The Linux NetKit FTP Server does not correctly drop privileges before changing into certain directories. This can be exploited to gain access to otherwise not accessible information and may allow to gain escalated privileges via symlink attacks if a NFS filesystem is used.
2) The return values of "seteuid()" and similar calls are not correctly checked. This can be exploited to perform certain actions with e.g. root privileges if the calls fail due to e.g. resource limits.
