> DESCRIPTION:
> A vulnerability has been reported in Sendmail, which can be exploited
> by malicious people to cause a DoS (Denial of Service).
> 
> The vulnerability is cause due to an error in the termination of the
> recursive "mime8to7()" function when performing MIME conversions.
> This can be exploited to cause a certain sendmail process to crash
> when it runs out of stack space while processing a deeply nested
> malformed MIME message.
> 
> Successful exploitation causes the delivery of other queued messages
> to fail or causes the generated core dump files to fill up available
> disk space.
> 
> The vulnerability has been reported in version 8.13.6 and prior.
> 
> SOLUTION:
> Update to version 8.13.7.
> 
> Users of the commercial products should see the patch matrix in the
> vendor advisory for details.
> 
> PROVIDED AND/OR DISCOVERED BY:
> The vendor credits Frank Sheiness.
