Several vulnerabilities have been discovered in the interpreter for the Python language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-2052     Piotr Engelking discovered that the strxfrm() function     of the locale module miscalculates the length of an     internal buffer, which may result in a minor information     disclosure.

  - CVE-2007-4965     It was discovered that several integer overflows in the     imageop module may lead to the execution of arbitrary     code, if a user is tricked into processing malformed     images. This issue is also tracked as CVE-2008-1679 due     to an initially incomplete patch.

  - CVE-2008-1721     Justin Ferguson discovered that a buffer overflow in the     zlib module may lead to the execution of arbitrary code.

  - CVE-2008-1887     Justin Ferguson discovered that insufficient input     validation in PyString_FromStringAndSize() may lead to     the execution of arbitrary code.

Specially crafted images could trigger an integer overflow in the imageop module. (CVE-2007-4965)

Red Hat Network Satellite Server version 5.1.1 is now available. This update includes fixes for a number of security issues in Red Hat Network Satellite Server Solaris client components.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

This release corrects several security vulnerabilities in components shipped as part of the Red Hat Network Satellite Server Solaris client. In a typical operating environment, these components are not used by the Satellite Server in a vulnerable manner. These security updates will reduce risk should these components be used by other applications.

Several flaws in Zlib were discovered. An attacker could create a carefully-crafted compressed stream that would cause an application to crash if the stream was opened by a user. (CVE-2005-2096, CVE-2005-1849)

A buffer overflow was discovered in the OpenSSL SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer (CVE-2006-3738).

A flaw in the SSLv2 client code was discovered. If a client application used OpenSSL to create an SSLv2 connection to a malicious server, that server could cause the client to crash. (CVE-2006-4343)

An attack on OpenSSL PKCS #1 v1.5 signatures was discovered. Where an RSA key with exponent 3 was used an attacker could, potentially, forge a PKCS #1 v1.5 signature that would be incorrectly verified by implementations that do not check for excess data in the RSA exponentiation result of the signature. This issue affected applications that use OpenSSL to verify X.509 certificates as well as other uses of PKCS #1 v1.5. (CVE-2006-4339)

OpenSSL contained a software work-around for a bug in SSL handling in Microsoft Internet Explorer version 3.0.2. It is enabled in most servers that use OpenSSL to provide support for SSL and TLS. This work-around was vulnerable to a man-in-the-middle attack which allowed a remote user to force an SSL connection to use SSL 2.0, rather than a stronger protocol, such as SSL 3.0 or TLS 1.0. (CVE-2005-2969)

During OpenSSL parsing of certain invalid ASN.1 structures, an error condition was mishandled. This could result in an infinite loop which consumed system memory (CVE-2006-2937).

Certain public key types could take disproportionate amounts of time to process in OpenSSL, leading to a denial of service. (CVE-2006-2940)

A flaw was discovered in the Python repr() function's handling of UTF-32/UCS-4 strings. If an application used the repr() function on untrusted data, this could lead to a denial of service or, possibly, allow the execution of arbitrary code with the privileges of the application using the flawed function. (CVE-2006-4980)

A flaw was discovered in the strxfrm() function of Python's locale module. Strings generated by this function were not properly NULL-terminated. This could, potentially, cause disclosure of data stored in the memory of an application using this function.
(CVE-2007-2052)

Multiple integer overflow flaws were discovered in Python's imageop module. If an application used the imageop module to process untrusted images, it could cause the application to crash, enter an infinite loop, or, possibly, execute arbitrary code with the privileges of the Python interpreter. (CVE-2007-4965)

A stack-based buffer overflow was discovered in the Python interpreter, which could allow a local user to gain privileges by running a script with a long name from the current working directory.
(CVE-2006-1542)

Users of Red Hat Network Satellite Server should upgrade to these updated packages, which contain backported patches to correct these issues.

From Red Hat Security Advisory 2007:1076 :

Updated python packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Python is an interpreted, interactive, object-oriented programming language.

An integer overflow flaw was discovered in the way Python's pcre module handled certain regular expressions. If a Python application used the pcre module to compile and execute untrusted regular expressions, it may be possible to cause the application to crash, or allow arbitrary code execution with the privileges of the Python interpreter. (CVE-2006-7228)

A flaw was discovered in the strxfrm() function of Python's locale module. Strings generated by this function were not properly NULL-terminated. This may possibly cause disclosure of data stored in the memory of a Python application using this function.
(CVE-2007-2052)

Multiple integer overflow flaws were discovered in Python's imageop module. If an application written in Python used the imageop module to process untrusted images, it could cause the application to crash, enter an infinite loop, or possibly execute arbitrary code with the privileges of the Python interpreter. (CVE-2007-4965)

Users of Python are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2009-1176 advisory.

    - Multiple integer overflows in python core (CVE-2008-2315)
    - PyString_FromStringAndSize does not check for negative size values (CVE-2008-1887)
    - Multiple integer overflows discovered by Google (CVE-2008-3143)
    - Multiple buffer overflows in unicode processing (CVE-2008-3142)
    - Potential integer underflow and overflow in the PyOS_vsnprintf C API function (CVE-2008-3144)
    - imageop module multiple integer overflows (CVE-2008-4864)
    - stringobject, unicodeobject integer overflows (CVE-2008-5031)
    - integer signedness error in the zlib extension module (CVE-2008-1721)
    - off-by-one locale.strxfrm() (possible memory disclosure) (CVE-2007-2052)
    - imageop module heap corruption (CVE-2007-4965)

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

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