|
|
|
The unirpc service listening on port 31438 is affected by various
|
|
Denial of Service vulnerabilities regarding the access of invalid zones
|
|
of memory.
|
|
|
|
Although the first vulnerability is a memory corruption problem where
|
|
the program calls recv() using a heap buffer and a huge amount of data
|
|
to copy (like 0x7fffffe8, decided by the attacker) in my tests it
|
|
didn't result exploitable.
