Hello,
please find attached a patch (one line) against xvidcore-1.1.0 that will
make libxvidcore.so.4.1' stack non-executable. Files with executable
stacks make trouble on pax-enabled systems.
This is how it should be
scanelf -e libxvidcore.so.4.1
TYPE STK/REL/PTL FILE
ET_DYN RW- --- RW- libxvidcore.so.4.1
This is how it is without:
scanelf -e libxvidcore.so.4.1
TYPE STK/REL/PTL FILE
ET_DYN RWX --- RW- libxvidcore.so.4.1
--
Regards
Sebastian Siewior
