Check for the version of the kernel packages Detailed Explanation for this Vulnerability Assessment Updated kernel packages that fix several security issues in the Red Hat Enterprise Linux 4 kernel are now available. This security advisory has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the security issues described below: * a flaw in the SCTP support that permited a local user to cause a denial of service (crash) with a specific SO_LINGER value. (CVE-2006-4535, Important) * a flaw in the hugepage table support that permited a local user to cause a denial of service (crash). (CVE-2005-4811, Important) * a flaw in the mprotect system call that permited setting write permission for a read-only attachment of shared memory. (CVE-2006-2071, Moderate) * a flaw in HID0[31] (en_attn) register handling on PowerPC 970 systems that permited a local user to cause a denial of service. (crash) (CVE-2006-4093, Moderate) * a flaw in the perfmon support of Itanium systems that permited a local user to cause a denial of service by consuming all file descriptors. (CVE-2006-3741, Moderate) * a flaw in the ATM subsystem. On systems with installed ATM hardware and configured ATM support, a remote user could cause a denial of service (panic) by accessing socket buffers memory after freeing them. (CVE-2006-4997, Moderate) * a flaw in the DVB subsystem. On systems with installed DVB hardware and configured DVB support, a remote user could cause a denial of service (panic) by sending a ULE SNDU packet with length of 0. (CVE-2006-4623, Low) * an information leak in the network subsystem that possibly permited a local user to read sensitive data from kernel memory. (CVE-2006-0039, Low) In addition, two bugfixes for the IPW-2200 wireless driver were included. The first one ensures that wireless management applications correctly identify IPW-2200 controlled devices, while the second fix ensures that DHCP requests using the IPW-2200 operate correctly. Red Hat would like to thank Olof Johansson, Stephane Eranian and Solar Designer for reporting issues fixed in this erratum. All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
