CAN-2003-0984: /dev/rtc leak An uninitialised buffer leaks a few bytes to user space. Made public by SuSE Dec04 although was not fixed upstream (at least as far as 2.4.22). This issue is fixed in our other distributions. The security implications are minor however at least one publication (ZDNet) decided to call this a critical security vulnerability, raising its profile out of all proportion.
actually fixed in 2.4.23, see http://linux.bkbits.net:8080/linux-2.4/cset@trini@mvista.com|ChangeSet|20040104192859|11383
The RHEL 3 fix for this problem was committed to the U2 patch pool tonight and will be available internally in kernel version 2.4.21-9.10.EL.
