The remote Amazon Linux AMI host is missing a security update.
A use-after-free flaw was found in the Linux kernel's memory
management subsystem in the way quota handling for huge pages was
performed. A local, unprivileged user could use this flaw to cause a
denial of service or, potentially, escalate their privileges.
(CVE-2012-2133 , Moderate)
A use-after-free flaw was found in the madvise() system call
implementation in the Linux kernel. A local, unprivileged user could
use this flaw to cause a denial of service or, potentially, escalate
their privileges. (CVE-2012-3511 , Moderate)
It was found that when running a 32-bit binary that uses a large
number of shared libraries, one of the libraries would always be
loaded at a predictable address in memory. An attacker could use this
flaw to bypass the Address Space Layout Randomization (ASLR) security
feature. (CVE-2012-1568 , Low)
Buffer overflow flaws were found in the udf_load_logicalvol() function
in the Universal Disk Format (UDF) file system implementation in the
Linux kernel. An attacker with physical access to a system could use
these flaws to cause a denial of service or escalate their privileges.
(CVE-2012-3400 , Low)
