| <description> |
| <p> |
| Ulf Harnhammar reported a possible buffer overflow in the handling |
| of TFTP URLs in libcurl due to the lack of boundary checks. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| An attacker could exploit this vulnerability to compromise a |
| user's system by enticing the user to request a malicious URL with |
| cURL/libcurl or to use a HTTP server redirecting to a malicious TFTP |
| URL. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All cURL users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.1-r1"</code> |
| </resolution> |
