  script_tag(name:"insight", value:"NFS did not correctly handle races between fcntl and interrupts. A local
attacker on an NFS mount could consume unlimited kernel memory, leading to
a denial of service. Ubuntu 8.10 was not affected. (CVE-2008-4307)

Sparc syscalls did not correctly check mmap regions. A local attacker
could cause a system panic, leading to a denial of service. Ubuntu 8.10
was not affected. (CVE-2008-6107)

In certain situations, cloned processes were able to send signals to parent
processes, crossing privilege boundaries. A local attacker could send
arbitrary signals to parent processes, leading to a denial of service.
(CVE-2009-0028)

The kernel keyring did not free memory correctly. A local attacker could
consume unlimited kernel memory, leading to a denial of service.
(CVE-2009-0031)

The SCTP stack did not correctly validate FORWARD-TSN packets. A remote
attacker could send specially crafted SCTP traffic causing a system crash,
leading to a denial of service. (CVE-2009-0065)

The eCryptfs filesystem did not correctly handle certain VFS return codes.
A local attacker with write-access to an eCryptfs filesystem could cause a
system crash, leading to a denial of service. (CVE-2009-0269)

The Dell platform device did not correctly validate user parameters. A
local attacker could perform specially crafted reads to crash the system,
leading to a denial of service. (CVE-2009-0322)

The page fault handler could consume stack memory. A local attacker could
exploit this to crash the system or gain root privileges with a Kprobe
registered. Only Ubuntu 8.10 was affected. (CVE-2009-0605)

Network interfaces statistics for the SysKonnect FDDI driver did not check
capabilities. A local user could reset statistics, potentially interfering
with packet accounting systems. (CVE-2009-0675)

The getsockopt function did not correctly clear certain parameters. A local
attacker could read leaked kernel memory, leading to a loss of privacy.
(CVE-2009-0676)

The ext4 filesystem did not correctly clear group descriptors when
resizing. A local attacker could exploit this to crash the system, leading
to a denial of service. (CVE-2009-0745)

The ext4 filesystem did not correctly validate certain fields. A local
attacker could mount a malicious ext4 filesystem, causing a system
crash, leading to a denial of service. (CVE-2009-0746, CVE-2009-0747,
CVE-2009-0748)

The syscall interface did not correctly validate parameters when crossing
the 64-bit/32-bit boundary. A local attacker could bypass certain syscall
restricts via crafted syscalls. (CVE-2009-0834, CVE-2009-0835)

The shared memory subsystem did not correctly handle certain shmctl calls
when CONFIG_SHMEM was disabled. Ubuntu kernels were not vulnerable, since
CONFIG_SHMEM is enabled by default. (CVE-2009-0859)

The virtual consoles did not correctly handle certain UTF-8 sequences. A
local attacker on the physical console could exploit this to cause a system
crash, leading to a denial of service. (CVE-2009-1046)");
