Descripción: | Description: The remote host is missing an update to libesmtp announced via advisory MDVSA-2010:195.
Multiple vulnerabilities has been found and corrected in libesmtp:
libESMTP, probably 1.0.4 and earlier, does not properly handle a \'\0\' (NUL) character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408 (CVE-2010-1192).
The match_component function in smtp-tls.c in libESMTP 1.0.3.r1, and possibly other versions including 1.0.4, treats two strings as equal if one is a substring of the other, which allows remote attackers to spoof trusted certificates via a crafted subjectAltName (CVE-2010-1194).
Packages for 2008.0 and 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
