Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2008:0607

The remote host is missing updates announced in
advisory RHSA-2008:0607.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

These updated packages fix the following security issue:

* a possible kernel memory leak was found in the Linux kernel Simple
Internet Transition (SIT) INET6 implementation. This could allow a local
unprivileged user to cause a denial of service. (CVE-2008-2136, Important)

As well, these updated packages fix the following bugs:

* a possible kernel hang on hugemem systems, due to a bug in NFS, which may
have caused systems to become unresponsive, has been resolved.

* an inappropriate exit condition occurred in the architecture-specific
mmap() realization, which fell into an infinite loop under certain
conditions. On 64-bit systems, this issue may have manifested itself to
users as a soft lockup, or process hangs.

* due to a bug in hardware initialization in the ohci_hcd kernel module,
the kernel may have failed with a NULL pointer dereference. On 64-bit
PowerPC systems, this may have caused booting to fail, and drop to xmon. On
other platforms, a kernel oops occurred.

* due to insufficient locks in task termination code, a panic may have
occurred in the sys_times() system call on SMP machines.

Red Hat Enterprise Linux 4 users are advised to upgrade to these updated
packages, which contain backported patches to resolve these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
