Title:	Amazon Linux: Security Advisory (ALAS-2014-380)
Summary:	The remote host is missing an update for the 'python27' package(s) announced via the ALAS-2014-380 advisory.
Description:	Summary: The remote host is missing an update for the 'python27' package(s) announced via the ALAS-2014-380 advisory. Vulnerability Insight: It was reported that Python built-in _json module have a flaw (insufficient bounds checking), which allows a local user to read current process' arbitrary memory. Quoting the upstream bug report: The sole prerequisites of this attack are that the attacker is able to control or influence the two parameters of the default scanstring function: the string to be decoded and the index. The bug is caused by allowing the user to supply a negative index value. The index value is then used directly as an index to an array in the C code, internally the address of the array and its index are added to each other in order to yield the address of the value that is desired. However, by supplying a negative index value and adding this to the address of the array, the processor's register value wraps around and the calculated value will point to a position in memory which isn't within the bounds of the supplied string, causing the function to access other parts of the process memory. Affected Software/OS: 'python27' package(s) on Amazon Linux. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
