CVE Name Pending
Description A 16 bit SMS message that contains an odd message length
value will cause the message decoding loop to run forever.
The message buffer is not on the stack but will be
overflowed resulting in corrupted memory and an immediate
crash.
Resolution This patch corrects the evaluation of the message length
indicator, ensuring that the message decoding loop will stop
at the end of the received message.
Thanks to Jan Juergens for finding, reporting, testing, and
providing a fix for this problem.
