When the BigDB variable tmm.ssl.loggingcreatedcerts is set, a buffer overflow can occur.
A off-by-one error causes one byte to write off the end of an array.
-- The BigDB variable tmm.ssl.loggingcreatedcerts is set. -- Forward proxy is being used. -- A malformed certificate with a serial number length equal to 256 bytes is parsed during forging.
There is no workaround other than to not set tmm.ssl.loggingcreatedcerts BigDB variable.
Buffer no longer overflows.
