Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2653-1 advisory.

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
