| <description> |
| <p> |
| Niels Heinen has discovered a buffer overflow in the socket_getline() |
| function of Newspost, which can be triggered by providing long strings |
| that do not end with a newline character. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could setup a malicious NNTP server and entice a |
| Newspost user to post to it, leading to the crash of the Newspost |
| process and potentially the execution of arbitrary code with the rights |
| of the Newspost user. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Newspost users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-nntp/newspost-2.0-r1"</code> |
