Description Warren Togami 2006-04-21 18:31:41 UTC

libflashplayer.so (7.0.63 and earlier) uses text relocations.  Text relocations
will soon be disallowed by selinux policies because it is a security risk.

Possible causes of text relocations:
1) Some code was not compiled with -fpic.
2) Hand written asm code that is not position independent.
3) Some compiler toolchain bug (possibly Bug #175442).

Ulrich Drepper recommends that Macromedia try FC5 as a development platform
because it contains the latest gcc and related compiling toolchains.  FC5
contains eu-findtextrel, whihc can aid in locating these problems.

Comment 1 Warren Togami 2006-06-26 21:34:38 UTC

There are two temporary workarounds for this problem for Fedora users, as we
wait for the next release of Flash Player that fixes this issue:

1) chcon -t textrel_shlib_t libflashplayer.so
   Do this on the file manually after Firefox has downloaded it to your home
directory.
2) http://macromedia.mplug.org/
   Use the flash-plugin RPM instead.

This is fixed in Flash Player 9 beta here:

Until Flash Player 9 is released, you can workaround this selinux denial problem
by using the Flash 7 RPM from:
