Title:
Possible null pointer dereferencing in
modules/ca/src/client/udpiiu.cpp
Status in EPICS Base:
In Progress
Bug description:
Codacy report an Error level issue on a possible null pointer
dereferencing modules/ca/src/client/udpiiu.cpp line 950.
If the function bool udpiiu::pushDatagramMsg ( epicsGuard < epicsMutex > & guard, const caHdr & msg, const void * pExt, ca_uint16_t extsize ) is called with the following parameters:
1) pExt == null
2) extsize > 0
This will cause the memcpy to read extsize bytes from null, presumably
crashing the code.
