Description: This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs. The following security issues were fixed: * CVE-2011-1093: The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly handle packets for a CLOSED endpoint, which allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet. * CVE-2011-2484: The add_del_listener function in kernel/taskstats.c in the Linux kernel did not prevent multiple registrations of exit handlers, which allowed local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application. * CVE-2011-1745: Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call. * CVE-2011-1746: Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel allowed local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. * CVE-2011-2022: The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 did not validate a certain start parameter, which allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745. * CVE-2011-1585: When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. * CVE-2011-0726: The do_task_stat function in fs/proc/array.c in the Linux kernel did not perform an expected uid check, which made it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary. * CVE-2011-2496: The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. * CVE-2011-2491: A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance. * CVE-2011-1017, CVE-2011-2182: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions. * CVE-2011-1593: Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel allowed local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call. * CVE-2011-1494: Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel might have allowed local users to gain privileges or cause a denial of service (memory corruption) via an ioctl call specifying a crafted value that triggers a heap-based buffer overflow. * CVE-2011-1495: drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel did not validate (1) length and (2) offset values before performing memory copy operations, which might have allowed local users to gain privileges, cause a denial of service (memory corruption), or obtain sensitive information from kernel memory via a crafted ioctl call, related to the _ctl_do_mpt_command and _ctl_diag_read_buffer functions.
