A remote attacker could send malicious replies to the server and cause smbd to use all available CPU, leading to a denial of service. (CVE-2009-2906) Ronald Volgers discovered that the mount.cifs utility, when installed as a setuid program, would not verify user permissions before opening a credentials file. A local user could exploit this to use or read the contents of unauthorized credential files. (CVE-2009-2948) Reinhard Nißl discovered that the smbclient utility contained format string vulnerabilities in its file name handling. Because of security features in Ubuntu, exploitation of this vulnerability is limited.
