Linux kernel vulnerabilities

Description

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)
