| Technical Description: |
Samba is vulnerable to several critical vulnerabilities. The most critical of these issues are heap-based buffer overflows, caused by improper bounds checking by the following functions:
- lsa_io_privilege_set (LSA RPC interface)
- mb_io_notify_option_type_data (SPOOLSS RPC interface)
- lsa_io_trans_names (LSA RPC interface)
By sending a specially-crafted RPC request to one of the affected interfaces, a remote attacker could overflow a buffer and execute arbitrary code on the system.
A fourth issue (34315, CVE-2007-2444) is a local privledge escalation that could allow a local attacker to gain elevated privileges on the system, caused by a logic error in the smbd internal stack. |
| Remediation: |
Apply the patch for this vulnerability or upgrade to the latest version of Samba (3.0.25 or later), available from the Samba Web site. See References. |
