Mandriva Linux Security Advisory MDVSA-2010:195 http://www.mandriva.com/security/


Package : libesmtp Date : October 4, 2010 Affected: 2008.0, 2009.0, 2009.1, 2010.0, 2010.1, Corporate 4.0, Enterprise Server 5.0


Problem Description:

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

The updated packages have been patched to correct these issues.
