Comment 1 Tomas Hoger 2008-03-19 12:53:50 UTC

Relevant part of Apple security advisory:

pax archive utility
CVE-ID:  CVE-2008-0992
Available for:  Mac OS X v10.5.2, Mac OS X Server v10.5.2
Impact:  Running the pax command on a maliciously crafted archive may
lead to arbitrary code execution
Description:  The pax command line tool does not check a length in
its input before using it as an array index, which may lead to an
unexpected application termination or arbitrary code execution. This
update addresses the issue by checking the index. This issue does not
affect systems prior to Mac OS X v10.5.


No further details available.

Comment 2 Tomas Hoger 2008-03-20 10:00:18 UTC

Apple clarified that this issue is specific to their version of pax as used in
Mac OS X Leopard and does not affect BSD pax version we ship.
