Description Tyson Whitehead 2011-10-27 02:56:28 UTC

Description of problem:

The 32bit dynamic linker and 32bit binaries just echo the command.  For example

$ file /lib/ld-2.13.so 
/lib/ld-2.13.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped
$ /lib/ld-2.13.so 
/lib/ld-2.13.so
$ file /sbin/grub
/sbin/grub: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.18, stripped
$ /sbin/grub
/sbin/grub

while the 64bit dynamic linker works as expected

$ /lib64/ld-2.13.so
Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]
...


Version-Release number of selected component (if applicable):

glibc-2.13-2.i686
glibc-2.13-2.x86_64
kernel-2.6.35.14-97.fc14.x86_64


How reproducible:

Always.


Steps to Reproduce:
1. Run a 32bit binary or the 32bit dynamic linker.

  
Actual results:

The command gets echoed.


Expected results:

The program runs.


Additional info:

Why was this reassigned to kernel ? There's nothing to suggest this isn't a problem with the linker.

Reassigning back to glibc.

Comment 2 Tyson Whitehead 2011-10-28 19:44:16 UTC

Turns out it was a temporary solution put into place for a CVE-2010-3081

https://access.redhat.com/kb/docs/DOC-40265

The exploit hole was closed back with 2.6.34.4-28.fc14

Sorry about the noise.  I'll close the ticket.

Cheers!  -Tyson
