From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; X11; Linux i686) Opera 7.23 [en] Description of problem: Crash binary (44 bytes) for the Linux kernel 2.4.21-20.EL and probably earlier versions, freezing the complete system, even when executed without root privileges. Version-Release number of selected component (if applicable): 2.4.21-20.EL (Red Hat Enterprise Linux AS release 3 / Taroon Update 3) How reproducible: Always Steps to Reproduce: 1.wget http://www.esat.kuleuven.ac.be/~wvereeck/kernel/exploit 2.chmod 755 exploit 3../exploit (as non-root) 4.freeze and cook up an excuse for your sysadmins Actual Results: The system freezes, so nothing world-astonishing happens. Expected Results: No crash/freeze, there are other OS's for this. Additional info: There seems to be a problem with the e_phnum byte in the ELF header, which crashes the linker/kernel, when it holds a zero.
