Description

Important: kernel security and bug fix updateThe kernel packages contain the Linux kernel, the core of any Linuxoperating system.These updated kernel packages fix the following security issues:A flaw was found in the virtual filesystem (VFS). A local unprivilegeduser could truncate directories to which they had write permission; thiscould render the contents of the directory inaccessible. (CVE-2008-0001,Important)A flaw was found in the implementation of ptrace. A local unprivileged usercould trigger this flaw and possibly cause a denial of service (systemhang). (CVE-2007-5500, Important)A flaw was found in the way the Red Hat Enterprise Linux 4 kernel handledpage faults when a CPU used the NUMA method for accessing memory on Itaniumarchitectures. A local unprivileged user could trigger this flaw and causea denial of service (system panic). (CVE-2007-4130, Important)A possible NULL pointer dereference was found in the chrp_show_cpuinfofunction when using the PowerPC architecture. This may have allowed a localunprivileged user to cause a denial of service (crash).(CVE-2007-6694, Moderate)A flaw was found in the way core dump files were created. If a local usercan get a root-owned process to dump a core file into a directory, whichthe user has write access to, they could gain read access to that corefile. This could potentially grant unauthorized access to sensitiveinformation. (CVE-2007-6206, Moderate)Two buffer overflow flaws were found in the Linux kernel ISDN subsystem. Alocal unprivileged user could use these flaws to cause a denial ofservice. (CVE-2007-6063, CVE-2007-6151, Moderate)As well, these updated packages fix the following bug:Red Hat Enterprise Linux 4 users are advised to upgrade to these updatedpackages, which contain backported patches to resolve these issues.
