kernel Kernel Update for SUSE Linux 10.1 Kernel Update für SUSE Linux 10.1 This kernel update brings the kernel to the one shipped with SLES 10 Service Pack 1 and also fixes the following security problems: - CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers. The default is that RH0 is disabled now. To adjust this, write to the file /proc/net/accept_source_route6. - CVE-2007-2453: The random number feature in the Linux kernel 2.6 (1) did not properly seed pools when there is no entropy, or (2) used an incorrect cast when extracting entropy, which might have caused the random number generator to provide the same values after reboots on systems without an entropy source. - 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. - 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 wakeup 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. - CVE-2007-3107: The signal handling in the Linux kernel, when run on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency. - CVE-2007-2525: Memory leak in the PPP over Ethernet (PPPoE) socket implementation in the Linux kernel allowed local users to cause a denial of service (memory consumption) by creating a socket using connect, and releasing it before the PPPIOCGCHAN ioctl is initialized. - CVE-2007-3513: The lcd_write function in drivers/usb/misc/usblcd.c in the Linux kernel did not limit the amount of memory used by a caller, which allowed local users to cause a denial of service (memory consumption). - CVE-2007-3851: On machines with a Intel i965 based graphics card local users with access to the direct rendering devicenode could overwrite memory on the machine and so gain root privileges. This kernel is not compatible to the previous SUSE Linux 10.1 kernel, so the Kernel Module Packages will need to be updated. Dieses Kernel Update bringt den Kernel auf den Stand von SLES 10 Service Pack 1 und behebt weiterhin folgende Sicherheitsprobleme (aufgelistet in englisch): - CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.

Dieser Kernel ist inkompatibel zu den früheren Kernel Module Paketen, die in einem seperaten Patch erneuert werden. security This update can be used to install a new kernel. If you decide to use the kernel update, we recommend that you reboot your system upon completion of the YaST Online Update, as additional kernel modules may be needed which can only be loaded after the system is rebooted. If you are in the course of performing a new installation, you should deselect this kernel update in order to avoid problems with the hardware detection during the installation. kernel-bigsmp i586 000951f58f5316c457ebf8a33717fe5d1c6c00dc kernel-debug i586 70d96b7e2647960f0baef1305d3ccd460c703fb7 kernel-debug x86_64 70d38a2b0bb631aa5e8cbf3c6452d2e53a3ffa11 kernel-default i586 1c03f5fdfdfcbc6337da878daeebb2fb7804b655 kernel-default ppc a09c21ab57acdf616a3c8c13480ddfe5b6503b13 kernel-default x86_64 9f7723ee73f58497884ac20e77458d837b30af97 kernel-iseries64 ppc 2cf0ac9dd1cb099435b9678045d9374444374db9 kernel-kdump i586 8726b442cfe347f1de2c340183042b0cd1225707 kernel-kdump ppc 23ded78a50ed81c0a0fe1debbe254635f6c55244 kernel-kdump x86_64 3e05709790cd18939dce28295aa5c10658b2541e kernel-ppc64 ppc dfb3e68c1ac40859eeed364577535b5dbd7b8471 kernel-smp i586 b0b6fe0b6a7f70526ec0cee110927cce4a4aa023 kernel-smp x86_64 bf3fdfe77340eb0ddded01da6cf0511b5e9bc5ae kernel-source i586 91774dc7624624fc0b38664db907ecc12c237b0f kernel-source ppc fb293b025e549b96c2600f9bdbd23025620b2c98 kernel-source x86_64 6cf09767d4792b42bee1b88104bd72490b972ef9 kernel-syms i586 6c7ca7bc83998ecc5c594471a1693d07ee2bffbc kernel-syms ppc 017a5c38bdcd5069af2e4eb64f43f19f6484652b kernel-syms x86_64 3abe53fa9a5b8c9d5c9dc7537ea04355567efe5b kernel-um i586 5829f511342d5341abc8c5d97b81d29105ee20b0 kernel-xen i586 f88bee44ca29f850749f9732d73c6227a2814a6e kernel-xen x86_64 37591f210b91377851b6c03e30c4bda8a07392ce kernel-xenpae i586 1aab277dbfb5973295383b1aa87aa125d43a2c21 kexec-tools i586 2f61fb65d6ca91cf3bf91fe550f6c6e09ea03bc4 kexec-tools x86_64 cc2f1b6e1e563ea6c81ec31f9553c84bfcaeb70c mkinitrd i586 34b3b409d494069617696e829e41ede062256412 mkinitrd ppc 61649a53e39364107e56e5f6ef163ced41e0014c mkinitrd x86_64 0fea82dcdc40c06cf3e09177a2dfeb15b6a74722 multipath-tools i586 6fb7e862b16389e53142fe07936f0ae104fa27eb multipath-tools ppc de1359c14d1b1e87384c4cf1e45f66beb852068f multipath-tools x86_64 dc436e0e79be765b796308723bc1951969ae8b5c open-iscsi i586 6240a8973f47ae19e4754598e5a9bae7895b5496 open-iscsi ppc c27672a26d7276521f90bbdce3cccf2eeefa7dcb open-iscsi x86_64 7e3b2cb053a893f5c54a7e3414f0869d1c8545dc udev i586 5a1534313734f3382747945ca814acd9e67cdb9f udev ppc f84c399ecc06723b8236301dde5b6e302339f034 udev x86_64 6cb42d8c3fe6ed3f7ae8073c97eab68308eabda2
