By sending a specially crafted email message, a remote attacker could exploit the buffer overflow in the "mail" utility to execute arbitrary code with the rights of the user running mail. Finally, a remote attacker can also trigger a Denial of Service by sending a malicious FETCH command to an affected imap4d, causing excessive resource consumption. </p> </impact> <workaround> <p> There are no known workarounds at this time. </p> </workaround> <resolution> <p> All GNU Mailutils users should upgrade to the latest available version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/mailutils-0.6-r1"</code> </resolution> <references> <uri link="https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1520">CAN-2005-1520</uri> <uri link="https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1521">CAN-2005-1521</uri> <uri link="https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1522">CAN-2005-1522</uri> <uri link="https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1523">CAN-2005-1523</uri> <uri link="http://www.idefense.com/application/poi/display?type=vulnerabilities&showYear=2005">iDEFENSE 05.25.05 advisories</uri> </references> <metadata tag="submitter" timestamp="2005-05-26T13:21:14Z"> DerCorny </metadata> <metadata tag="bugReady" timestamp="2005-05-27T07:50:06Z"> koon </metadata> </glsa>
