The remote host is missing an update for the 'linux-fsl-imx51' package(s) announced via the USN-1074-1 advisory.
Vulnerability Insight:
Al Viro discovered a race condition in the TTY driver. A local attacker
could exploit this to crash the system, leading to a denial of service.
(CVE-2009-4895)
Dan Rosenberg discovered that the MOVE_EXT ext4 ioctl did not correctly
check file permissions. A local attacker could overwrite append-only files,
leading to potential data loss. (CVE-2010-2066)
Dan Rosenberg discovered that the swapexit xfs ioctl did not correctly
check file permissions. A local attacker could exploit this to read from
write-only files, leading to a loss of privacy. (CVE-2010-2226)
Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory
manager did not properly handle when applications grow stacks into adjacent
memory regions. A local attacker could exploit this to gain control of
certain applications, potentially leading to privilege escalation, as
demonstrated in attacks against the X server. (CVE-2010-2240)
Suresh Jayaraman discovered that CIFS did not correctly validate certain
response packets. A remote attacker could send specially crafted traffic
that would crash the system, leading to a denial of service.
(CVE-2010-2248)
Ben Hutchings discovered that the ethtool interface did not correctly check
certain sizes. A local attacker could perform malicious ioctl calls that
could crash the system, leading to a denial of service. (CVE-2010-2478,
CVE-2010-3084)
James Chapman discovered that L2TP did not correctly evaluate checksum
capabilities. If an attacker could make malicious routing changes, they
could crash the system, leading to a denial of service. (CVE-2010-2495)
Neil Brown discovered that NFSv4 did not correctly check certain write
requests. A remote attacker could send specially crafted traffic that could
crash the system or possibly gain root privileges. (CVE-2010-2521)
David Howells discovered that DNS resolution in CIFS could be spoofed. A
local attacker could exploit this to control DNS replies, leading to a loss
of privacy and possible privilege escalation. (CVE-2010-2524)
Dan Rosenberg discovered that the btrfs filesystem did not correctly
validate permissions when using the clone function. A local attacker could
overwrite the contents of file handles that were opened for append-only, or
potentially read arbitrary contents, leading to a loss of privacy. Only
Ubuntu 9.10 was affected. (CVE-2010-2538)
Bob Peterson discovered that GFS2 rename operations did not correctly
validate certain sizes. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-2798)
Kees Cook discovered that under certain situations the ioctl subsystem for
DRM did not properly sanitize its arguments. A local attacker could exploit
this to read previously freed kernel memory, leading to a loss of privacy.
(CVE-2010-2803)
Eric Dumazet discovered that many network functions could leak kernel stack
contents. A local attacker could exploit ... [Please see the references for more information on the vulnerabilities]
