[USN-2542-1] Linux kernel (OMAP4) vulnerabilities

Severity High

CVEs 8

Several security issues were fixed in the kernel.

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 how Thread Local Storage (TLS) is handled by the
task switching function in the Linux kernel for x86_64 based machines. A
local user could exploit this flaw to bypass the Address Space Layout
Radomization (ASLR) protection mechanism. (CVE-2014-9419)

Dmitry Chernenkov discovered a buffer overflow in eCryptfs' encrypted file
name decoding. A local unprivileged user could exploit this flaw to cause a
denial of service (system crash) or potentially gain administrative
privileges. (CVE-2014-9683)

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 malicous
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
malicous 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 malicous 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 malicous UDF file
system image, could exploit this flaw to read potential sensitve kernel
memory. (CVE-2014-9731)

Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP
(Stream Control Transmission Protocol) subsystem during INIT collisions. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) or potentially escalate their privileges on the system.
