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

Ubuntu Security Notice (C) 2012-2014 Canonical, Inc. / NASL script (C) 2012-2014 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 automatated 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).

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
