Details:
Hello Folks,
while trying to test a gnusetp-base 1.14.2 rpm pkg that I put together (with
the autogsdoc binary from that pkg) on a Rhel5.1-Server-i386 platform with
SELinux enabled (this is a must for us), I identified the cases below. Have
you seen similar problems? In all the cases below, the following were used:
gnustep-make 2.0.5
gnustep-base 1.14.2
ffcall 1.10
I have seen the same on Rhel5.1 and Fedora 8 x86_64 platforms also. Updating
to gnustep-base 1.14.3 with libffi 3.0.5 still results in buffer overflow for
autogsdoc and some of the other gnustep-base binaries.
Best regards,
Gareth
1) SELinux Enabled, no tweaks.
[root@shrek6 ~]# autogsdoc
trampoline: cannot make memory executable
Aborted (core dumped)
Replacing ffcall with libffi 3.0.5 (http://sourceware.org/libffi/) corrects
this problem and is probably the way to go to be clean. gnustep-base compiles
cleanly with libffi but still results in case 2 below. libffi is now actively
maintained which is not the case with ffcall. However, even with libffi,
autogsdoc still has a buffer overflow.
2) SELinux Enabled but tweaked to "Allow unconfined executables to make their
heap memory executable..." (VERY bad idea).
