freebsd security - Apr 2013 - Mac OS 10.5 & 10.6 kernel panic when mounting ppc 9.0 iso/CD

Hi,

 I tried installing FreeBSD 9.0 ppc yesterday. In preparing a CD, as soon as the
disc finished burning and mounted on the desktop I had a crash/kernel panic in
Mac OS 10.5.8 running on a G5 2 GHz tower, resulting in disk damage. I thought
that was interesting so inserted the CD in a 2008 iMac running Mac OS 10.6.,
also immediately followed by a kernel crash with mounting to the desktop. Other
than inserting the CD no user interventions were necessary. Downloaded the iso
twice -1st try was 4/5/13, 2nd was yesterday. Do not know whether this is
expected behavior but a warning would have been nice. Am writing in case this
was a malicious event or tampering with the source file. Ran ClamXav on the HD
disc and did not find anything, but didn't try to mount and scan the iso
because of above.


Thanks,
