Known Affected Releases

unspecified

Description (partial)

Symptom:The MCU DSP decoder could fail to decode the tail of some encrypted packets where they were encrypted without padding. This could lead to no video and in rare circumstances, an unexpected restart. 
Condition: MCU decoding encrypted calls where some incoming encrypted bit stream do not have padding. This is another case of invalid bit-stream which could cause problems with the DSP decoder. 
Workaround: No work around available. This is fixed as part of decoder resiliency improvement and addressed in 4.3(2.30) and later code.
