Description Jan Lieskovsky 2007-12-14 16:30:35 UTC

Description of problem:

Fix possible memory overrun issue in the isdn ioctl code.

The 1 snprintf() can be overflown by people who also use
the ioctl. It however can only overwrite other parts of
the iocpar union, no return pointers.

This issue public via:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=eafe1aa37e6ec2d56f14732b5240c4dd09f0613a

The above link also includes the proposed patch.

Note:

This issue is different than that one described in:

https://bugzilla.redhat.com/show_bug.cgi?id=392101

which is also I4L kernel ISDN code related.
