A flaw was reported in fetchmail where, when running in debug mode (-v -v), fetchmail prints information that was obtained from the upstream server (via POP3 UIDL list) or from message headers retrieved from it. If printing such information fails, perhaps due to invalid multibyte character sequences in this information, fetchmail will misinterpret this condition, and believe the buffer was too small. It will then reallocate a bigger one, with linearly increasing buffer size, and will continue to repeat this until the allocation fails, at which point fetchmail will abort. This issue has been assigned CVE-2010-1167 and will be upstream fetchmail-SA-2010-02 [1]. A fix has already been committed upstream [2] and will be in the forthcoming 6.3.17 version.
