Description

These new kernel packages contain fixes for the following security issues :

  • A flaw was found in the backported stack unwinder fixes in Red Hat Enterprise Linux 5. On AMD64 and Intel 64 platforms, a local user could trigger this flaw and cause a denial of service. (CVE-2007-4574, Important)

  • A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling. (CVE-2007-3848, Important)

  • A flaw was found in the Distributed Lock Manager (DLM) in the cluster manager. This allowed a remote user who is able to connect to the DLM port to cause a denial of service. (CVE-2007-3380, Important)

  • A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver which should otherwise be restricted to privileged users. (CVE-2007-4308, Moderate)

  • A flaw was found in the prio_tree handling of the hugetlb support that allowed a local user to cause a denial of service. This only affected kernels with hugetlb support. (CVE-2007-4133, Moderate)

  • A flaw was found in the eHCA driver on PowerPC architectures that allowed a local user to access 60k of physical address space. This address space could contain sensitive information. (CVE-2007-3850, Moderate)

  • A flaw was found in ptrace support that allowed a local user to cause a denial of service via a NULL pointer dereference. (CVE-2007-3731, Moderate)

  • A flaw was found in the usblcd driver that allowed a local user to cause a denial of service by writing data to the device node. To exploit this issue, write access to the device node was needed. (CVE-2007-3513, Moderate)

  • A flaw was found in the random number generator implementation that allowed a local user to cause a denial of service or possibly gain privileges. If the root user raised the default wakeup threshold over the size of the output pool, this flaw could be exploited. (CVE-2007-3105, Low)

In addition to the security issues described above, several bug fixes preventing possible system crashes and data corruption were also included.
