"The openSUSE 11.0 kernel was updated to 2.6.25.9.

It fixes two security problems: CVE-2008-2372: A resource starvation
issue within mmap was fixed, which could have been used by local
attackers to hang the machine.

CVE-2008-2826: A integer overflow in SCTP was fixed, which might have
been used by remote attackers to crash the machine or potentially
execute code.

The update also has lots of other bugfixes that are listed in the RPM
changelog."
