Description Jan Lieskovsky 2007-11-12 11:31:29 UTC

Description of problem:

Buffer overflow in the (1) sysfs_show_available_clocksources and (2)
sysfs_show_current_clocksources functions in Linux kernel 2.6.23 and
earlier might allow local users to cause a denial of service or
execute arbitrary code via crafted clock source names. (CVE-2007-5908).

Comment 3 Chuck Ebbert 2007-11-12 20:56:51 UTC

This does not look like it can actually happen. The list of available
clocksources is very short and they all have short names.

Comment 4 Eric Sandeen 2007-11-30 05:31:21 UTC

So far looks like nothing committed upstream on this one, either.

Comment 5 Jan Lieskovsky 2007-11-30 13:20:05 UTC

Re: c#3: Chuck so this means, you don't want to fix this one?

Comment 6 Jan Lieskovsky 2007-11-30 13:21:02 UTC

Re: c#4: Eric, maybe you could initiate the commit to RH kernel mailing list?

Comment 7 Jan Lieskovsky 2008-03-12 10:28:10 UTC

Based on c#3 and further investigation closing this one as WONTFIX.
