Proposal for a fix
2.6 kernels have solved this issue by using READ_IMPLIES_EXEC personality.
This problem was resolved in the RHEL3 U4 kernel on 1-Dec-2004 (in kernel version 2.4.21-27.EL). *** This bug has been marked as a duplicate of 137464 *** An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2004-550.html |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) Description of problem: For a legacy binary(which doesn't have PT_GNU_STACK program header and assumes READ implies EXEC behaviour), kernel is mapping data segment as not executable. Because of this issue java doesn't run on a processor which supports 'execute disable' feature Version-Release number of selected component (if applicable): kernel-2.4.21-20.EL How reproducible: Always Steps to Reproduce: 1.Boot the x86 kernel on a processor which supports exec disable feature 2.Run java. It hangs with recursive seg faults. 3. Additional info:
