Hi,

I cannot run an executable if it is named setlang (case insensitive).
It exits with code 127.

Example:
cp /bin/ls setlang
./setlang -> Error 127

I've noticed a difference in ldd output. cygwin dlls appear twice.

ldd /bin/ls:
        ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffd9be50000)
        KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL
(0x7ffd9bbb0000)
        KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll
(0x7ffd9b8e0000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000)
        cygintl-8.dll => /usr/bin/cygintl-8.dll (0x3ff810000)
        cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3ff830000)

ldd setlang:
        ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffd9be50000)
        KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL
(0x7ffd9bbb0000)
        KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll
(0x7ffd9b8e0000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0xc10000)
        cygintl-8.dll => /usr/bin/cygintl-8.dll (0x170000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0xc10000)
        cygintl-8.dll => /usr/bin/cygintl-8.dll (0x170000)
        cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x600000)
        cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x600000)

Any idea what can cause this?

Thanks,
- Orgad

Isn't this the same issue with:

Probably you have "setlang.exe" entry in "Program settings" in
Exploit Protection.

Yup, looks like it. Thanks for the reference. We even used the same example :D
