SynopsisThe remote openSUSE host is missing a security update.
DescriptionThe openSUSE 11.4 kernel was updated to 18.104.22.168 fixing lots of bugs and security issues.
Following security issues have been fixed: CVE-2011-2495: The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar.
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-2011-2022: The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 22.214.171.124 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-2011-1745: 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-2011-2493: A denial of service on mounting invalid ext4 filesystems was fixed.
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-2011-2498: Also account PTE pages when calculating OOM scoring, which could have lead to a denial of service.
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-2011-1017,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-2011-1479: A regression in inotify fix for a memory leak could lead to a double free corruption which could crash the system.
CVE-2011-1927: A missing route validation issue in ip_expire() could be used by remote attackers to trigger a NULL ptr dereference, crashing parts of the kernel.
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-2011-1020: The proc filesystem implementation in the Linux kernel did not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allowed local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls.
SolutionUpdate the affected kernel packages.
