 Mandriva Linux Security Advisory                         MDVSA-2011:107
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : fetchmail
 Date    : June 7, 2011
 Affected: 2009.0, 2010.1, Corporate 4.0, Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 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:
 http://store.mandriva.com/product_info.php?cPath=149&products_id=490
 
 The updated packages have been upgraded to the 6.3.20 version which
 is not vulnerable to these issues.
