| Description: | Summary:
The remote host is missing an update for the 'linux' package(s) announced via the USN-2544-1 advisory.
Vulnerability Insight:
Eric Windisch discovered flaw in how the Linux kernel's XFS file system
replaces remote attributes. A local access with access to an XFS file
system could exploit this flaw to escalate their privileges.
(CVE-2015-0274)
A flaw was discovered in the automatic loading of modules in the crypto
subsystem of the Linux kernel. A local user could exploit this flaw to load
installed kernel modules, increasing the attack surface and potentially
using this to gain administrative privileges. (CVE-2013-7421)
The Linux kernel's splice system call did not correctly validate its
parameters. A local, unprivileged user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-7822)
A flaw was discovered in the crypto subsystem when screening module names
for automatic module loading if the name contained a valid crypto module
name, eg. vfat(aes). A local user could exploit this flaw to load installed
kernel modules, increasing the attack surface and potentially using this to
gain administrative privileges. (CVE-2014-9644)
Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) failed to
verify symlink size info. A local attacker, who is able to mount a malicious
UDF file system image, could exploit this flaw to cause a denial of service
(system crash) or possibly cause other undesired behaviors. (CVE-2014-9728)
Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) did not
valid inode size information . A local attacker, who is able to mount a
malicious UDF file system image, could exploit this flaw to cause a denial
of service (system crash) or possibly cause other undesired behaviors.
(CVE-2014-9729)
Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) did not
correctly verify the component length for symlinks. A local attacker, who
is able to mount a malicious UDF file system image, could exploit this flaw
to cause a denial of service (system crash) or possibly cause other
undesired behaviors. (CVE-2014-9730)
Carl H Lunde discovered an information leak in the UDF file system
(CONFIG_UDF_FS). A local attacker, who is able to mount a malicious UDF file
system image, could exploit this flaw to read potential sensitive kernel
memory. (CVE-2014-9731)
Affected Software/OS:
'linux' package(s) on Ubuntu 14.04.
