The remote Scientific Linux host is missing one or more security
* 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.
* 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)
