An unspecified kernel interface in Mac OS X 10.4.2 and earlier does not properly clear memory before reusing it, which could allow attackers to obtain sensitive information, a different vulnerability than CVE-2005-1126 and CVE-2005-1406.

The kernel in FreeBSD 4.x to 4.11 and 5.x to 5.4 does not properly clear certain fixed-length buffers when copying variable-length data for use by applications, which could allow those applications to read previously used sensitive memory.
