Paxtest reports vulnerabilities

[cmouse]

I ran paxtest and it says that I am still vulnerable for

Return to function (strcpy) :
Return to function (strcpy, RANDEXEC) :
Return to function (memcpy) : Vulnerable
Return to function (memcpy, RANDEXEC) : Vulnerable

Is there anything I can do to prevent this? Or would this require custom compilation of libc?

yes, you could for example search this very forum and find stuff like this http://forums.grsecurity.net/viewtopic.php?f=3&t=2084&p=8616#p8616 .

Or would this require custom compilation of libc?

the tested functions are only a simple representation of a much more generic attack metod and changing glibc wouldn't do anything against that.
