Mandriva Linux Security Advisory : fetchmail (MDVSA-2011:107)

Medium Nessus Plugin ID 54991


The remote Mandriva Linux host is missing one or more security updates.


Multiple vulnerabilities were discovered and corrected in fetchmail :

fetchmail 4.6.3 through 6.3.16, when debug mode is enabled, does not properly handle invalid characters in a multi-character locale, which allows remote attackers to cause a denial of service (memory consumption and application crash) via a crafted (1) message header or (2) POP3 UIDL list (CVE-2010-1167). NOTE: This vulnerability did not affect Mandriva Linux 2010.2.

fetchmail 5.9.9 through 6.3.19 does not properly limit the wait time after issuing a (1) STARTTLS or (2) STLS request, which allows remote servers to cause a denial of service (application hang) by acknowledging the request but not sending additional packets (CVE-2011-1947).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more: products_id=490

The updated packages have been upgraded to the 6.3.20 version which is not vulnerable to these issues.


Update the affected fetchmail, fetchmail-daemon and / or fetchmailconf packages.
