Ubuntu 10.04 LTS / 11.04 : python3.1 vulnerabilities (USN-1616-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

It was discovered that Python would prepend an empty string to
sys.path under certain circumstances. A local attacker with write
access to the current working directory could exploit this to execute
arbitrary code. This issue only affected Ubuntu 10.04 LTS.
(CVE-2008-5983)

It was discovered that the audioop module did not correctly perform
input validation. If a user or automated system were tricked into
opening a crafted audio file, an attacker could cause a denial of
service via application crash. These issues only affected Ubuntu 10.04
LTS. (CVE-2010-1634, CVE-2010-2089)

It was discovered that Python distutils contained a race condition
when creating the ~/.pypirc file. A local attacker could exploit this
to obtain sensitive information. (CVE-2011-4944)

It was discovered that SimpleXMLRPCServer did not properly validate
its input when handling HTTP POST requests. A remote attacker could
exploit this to cause a denial of service via excessive CPU
utilization. (CVE-2012-0845)

It was discovered that Python was susceptible to hash algorithm
attacks. An attacker could cause a denial of service under certian
circumstances. This update adds the '-R' command line option and
honors setting the PYTHONHASHSEED environment variable to 'random' to
salt str and datetime objects with an unpredictable value.
(CVE-2012-1150)

Serhiy Storchaka discovered that the UTF16 decoder in Python did not
properly reset internal variables after error handling. An attacker
could exploit this to cause a denial of service via memory corruption.
(CVE-2012-2135).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected python3.1 and / or python3.1-minimal packages.

Risk factor :

Medium / CVSS Base Score : 6.9
(CVSS2#AV:L/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 6.0
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
