| <affected> |
| <package name="mail-mta/xmail" auto="yes" arch="*"> |
| <unaffected range="ge">1.22</unaffected> |

| <description> |
| <p> |
| iDEFENSE reported that the AddressFromAtPtr function in the |
| sendmail program fails to check bounds on arguments passed from other |
| functions, and as a result an exploitable stack overflow condition |
| occurs when specifying the "-t" command line option. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A local attacker can make a malicious call to sendmail, |
| potentially resulting in code execution with elevated privileges. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Xmail users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=mail-mta/xmail-1.22"</code> |
| </resolution> |
