======================================================
Name: CVE-2008-2711
Status: Candidate
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2711
Reference: MLIST:[oss-security] 20080613 CVE Id Request: fetchmail <= 6.3.8 DoS when logging long headers in -v -v mode
Reference: URL:http://www.openwall.com/lists/oss-security/2008/06/13/1
Reference: MISC:https://bugzilla.novell.com/show_bug.cgi?id=354291

fetchmail 6.3.8 and earlier, when running in -v -v mode, allows remote
attackers to cause a denial of service (crash and persistent mail
failure) via a malformed mail message with long headers, which is not
properly handled when using vsnprintf to format log messages.
