| Description: | Summary:
The remote host is missing an update for the 'linux, linux-source-2.6.15, linux-source-2.6.22' package(s) announced via the USN-659-1 advisory.
Vulnerability Insight:
It was discovered that the direct-IO subsystem did not correctly validate
certain structures. A local attacker could exploit this to cause a system
crash, leading to a denial of service. (CVE-2007-6716)
It was discovered that the disabling of the ZERO_PAGE optimization could
lead to large memory consumption. A local attacker could exploit this to
allocate all available memory, leading to a denial of service.
(CVE-2008-2372)
It was discovered that the Datagram Congestion Control Protocol (DCCP) did
not correctly validate its arguments. If DCCP was in use, a remote attacker
could send specially crafted network traffic and cause a system crash,
leading to a denial of service. (CVE-2008-3276)
It was discovered that the SBNI WAN driver did not correctly check for the
NET_ADMIN capability. A malicious local root user lacking CAP_NET_ADMIN
would be able to change the WAN device configuration, leading to a denial
of service. (CVE-2008-3525)
It was discovered that the Stream Control Transmission Protocol (SCTP) did
not correctly validate the key length in the SCTP_AUTH_KEY option. If SCTP
is in use, a remote attacker could send specially crafted network traffic
that would crash the system, leading to a denial of service.
(CVE-2008-3526)
It was discovered that the tmpfs implementation did not correctly handle
certain sequences of inode operations. A local attacker could exploit this
to crash the system, leading to a denial of service. (CVE-2008-3534)
It was discovered that the readv/writev functions did not correctly handle
certain sequences of file operations. A local attacker could exploit this
to crash the system, leading to a denial of service. (CVE-2008-3535)
It was discovered that SCTP did not correctly validate its userspace
arguments. A local attacker could call certain sctp_* functions with
malicious options and cause a system crash, leading to a denial of service.
(CVE-2008-3792, CVE-2008-4113, CVE-2008-4445)
It was discovered the i915 video driver did not correctly validate
memory addresses. A local attacker could exploit this to remap memory
that could cause a system crash, leading to a denial of service.
(CVE-2008-3831)
Johann Dahm and David Richter discovered that NFSv4 did not correctly
handle certain file ACLs. If NFSv4 is in use, a local attacker could create
a malicious ACL that could cause a system crash, leading to a denial of
service. (CVE-2008-3915)
