Ubuntu 6.06 LTS : linux-source-2.6.15 vulnerabilities (USN-752-1)

Ubuntu Security Notice (C) 2009-2015 Canonical, Inc. / NASL script (C) 2009-2015 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

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. (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.

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 64-bit syscall interfaces did not correctly handle sign extension.
A local attacker could make malicious syscalls, possibly gaining root
privileges. The x86_64 architecture was not affected. (CVE-2009-0029)

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 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)

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 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,

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).

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
