| <description> |
| <p>Multiple vulnerabilities have been discovered in bip:</p> |
| |
| <ul> |
| <li>Uli Schlachter reported that bip does not properly handle invalid |
| data during authentication, resulting in a daemon crash |
| (CVE-2010-3071). |
| </li> |
| <li>Julien Tinnes reported that bip does not check the number of open |
| file descriptors against FD_SETSIZE, resulting in a stack buffer |
| overflow (CVE-2012-0806). |
| </li> |
| </ul> |
| </description> |
| <impact type="high"> |
| <p>A remote attacker could exploit these vulnerabilities to execute |
| arbitrary code with the privileges of the user running the bip daemon, or |
| cause a Denial of Service condition. |
| </p> |
| </impact> |
| <workaround> |
| <p>There is no known workaround at this time.</p> |
| </workaround> |
| <resolution> |
| <p>All bip users should upgrade to the latest version:</p> |
| |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-irc/bip-0.8.8-r1" |
| </code> |
| |
| <p>NOTE: The CVE-2010-3071 flaw was already corrected in an earlier version |
| of bip and is included in this advisory for completeness. |
