| <title>ncpfs: Multiple vulnerabilities</title> |
| <synopsis> |
| The ncpfs utilities contain multiple flaws, potentially resulting in the |
| remote execution of arbitrary code or local file access with elevated |
| privileges. |

| <p> |
| ncpfs is a NCP protocol network filesystem driver that allows |
| access to NetWare services, to mount volumes of NetWare servers or |
| print to NetWare print queues. |
| </p> |
| </background> |
| <description> |
| <p> |
| Erik Sjolund discovered two vulnerabilities in the programs |
| bundled with ncpfs: there is a potentially exploitable buffer overflow |
| in ncplogin (CAN-2005-0014), and due to a flaw in nwclient.c, utilities |
| using the NetWare client functions insecurely access files with |
| elevated privileges (CAN-2005-0013). |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| The buffer overflow might allow a malicious remote NetWare server |
| to execute arbitrary code on the NetWare client. Furthermore, a local |
| attacker may be able to create links and access files with elevated |
| privileges using SUID ncpfs utilities. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All ncpfs users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-fs/ncpfs-2.2.6"</code> |
| </resolution> |
