Product(s): SUSE CORE 9 for IBM zSeries 64bit
- CVE-2007-2876: A NULL pointer dereference in SCTP connection tracking could be caused by a remote attacker by sending specially crafted packets. Note that this requires SCTP set-up and active to be exploitable. This bug was already fixed in openSUSE 10.2 and SLES10.
- The handling of the usage counter for bond devices was fixed.
- CVE-2007-3105: Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wake-up threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving "bound check ordering". Since this value can only be changed by a root user, exploitability is low. This was already fixed for SLES10.
- CVE-2007-2525: A memory leak in the PPPoE driver can be abused by local users to cause a denial-of-service condition. This bug was already fixed for SLES10.
- CVE-2007-3848: Local users are allowed to send arbitrary signals to child processes running with different UID. This bug was already fixed for SLES10
- CVE-2007-4573: It was possible for local user to become root by exploiting a bug in the IA32 system call emulation. This affects x86_64 platforms with kernel 2.4.x and 2.6.x before 22.214.171.124 only.
- CVE-2007-4571: An information disclosure vulnerability in the ALSA driver can be exploited by local users to read sensitive data from the kernel memory.

When rebooting the Linux on zSeries z/VM guests, please ensure that you have installed the PTFs for APAR VM63742:
- z/VM 4.4: UM31426
- z/VM 5.1: UM31428
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
