CVE-2014-4616

Array index error in the scanstring function in the _json module in Python 2.7 through 3.5 and simplejson before 2.6.1 allows context-dependent attackers to read arbitrary process memory via a negative index value in the idx argument to the raw_decode function.

Updated python and python3 packages fix security vulnerabilities:

Python 2 and 3 are susceptible to arbitrary process memory reading by a user or adversary due to a bug in the _json module caused by insufficient bounds checking. The bug is caused by allowing the user to supply a negative value that is used as an array index, causing the scanstring function to access process memory outside of the string it is intended to access (CVE-2014-4616).

The CGIHTTPServer Python module does not properly handle URL-encoded path separators in URLs. This may enable attackers to disclose a CGI script's source code or execute arbitrary scripts in the server's document root (CVE-2014-4650).

This issue also affected the python-simplejson package, which has been patched to fix the bug.

It was discovered that multiple Python protocol libraries incorrectly limited certain data when connecting to servers. A malicious ftp, http, imap, nntp, pop or smtp server could use this issue to cause a denial of service. (CVE-2013-1752)

It was discovered that the Python xmlrpc library did not limit unpacking gzip-compressed HTTP bodies. A malicious server could use this issue to cause a denial of service. (CVE-2013-1753)

It was discovered that the Python json module incorrectly handled a certain argument. An attacker could possibly use this issue to read arbitrary memory and expose sensitive information. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-4616)

It was discovered that the Python CGIHTTPServer incorrectly handled URL-encoded path separators in URLs. A remote attacker could use this issue to expose sensitive information, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-4650)

It was discovered that Python incorrectly handled sizes and offsets in buffer functions. An attacker could possibly use this issue to read arbitrary memory and obtain sensitive information. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-7185)
