▸ GLSA 200807-16 Python: Multiple vulnerabilities this version unaffected normal remote 2008-07-31

Multiple vulnerabilities in Python may allow for the execution of arbitrary code.

Announced: 2008-07-31
Revised: 2009-07-19 (revision 2)
Access: remote
Bugs: #230640 #232137
Advisory: https://security.gentoo.org/glsa/200807-16

Affected packages

Package	Arch	Vulnerable	Unaffected
dev-lang/python	*	< 2.5.2-r6	>= 2.4.4-r14 (revision), >= 2.5.2-r6, >= 2.4.6 (revision)

Background

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

Description

Multiple vulnerabilities were discovered in Python:

David Remahl of Apple Product Security reported several integer overflows in core modules such as stringobject, unicodeobject, bufferobject, longobject, tupleobject, stropmodule, gcmodule, mmapmodule (CVE-2008-2315).
David Remahl of Apple Product Security also reported an integer overflow in the hashlib module, leading to unreliable cryptographic digest results (CVE-2008-2316).
Justin Ferguson reported multiple buffer overflows in unicode string processing that only affect 32bit systems (CVE-2008-3142).
The Google Security Team reported multiple integer overflows (CVE-2008-3143).
Justin Ferguson reported multiple integer underflows and overflows in the PyOS_vsnprintf() function, and an off-by-one error when passing zero-length strings, leading to memory corruption (CVE-2008-3144).

Impact

A remote attacker could exploit these vulnerabilities in Python applications or daemons that pass user-controlled input to vulnerable functions. Exploitation might lead to the execution of arbitrary code or a Denial of Service. Vulnerabilities within the hashlib might lead to weakened cryptographic protection of data integrity or authenticity.

Workaround

There is no known workaround at this time.

Resolution

All Python 2.4 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.4-r14"

All Python 2.5 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.5.2-r6"

Please note that Python 2.3 is masked since June 24, and we will not be releasing updates to it. It will be removed from the tree in the near future.

Background

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

Description

Multiple vulnerabilities were discovered in Python:

David Remahl reported multiple integer overflows in the file imageop.c, leading to a heap-based buffer overflow (CVE-2008-1679). This issue is due to an incomplete fix for CVE-2007-4965.
Justin Ferguson discovered that an integer signedness error in the zlib extension module might trigger insufficient memory allocation and a buffer overflow via a negative signed integer (CVE-2008-1721).
Justin Ferguson discovered that insufficient input validation in the PyString_FromStringAndSize() function might lead to a buffer overflow (CVE-2008-1887).

Impact

A remote attacker could exploit these vulnerabilities to cause a Denial of Service or possibly the remote execution of arbitrary code with the privileges of the user running Python.

Workaround

There is no known workaround at this time.

Resolution

The imageop module is no longer built in the unaffected versions.

▸ GLSA 200509-08 Python: Heap overflow in the included PCRE library this version unaffected normal remote 2005-09-12

The "re" Python module is vulnerable to a heap overflow, possibly leading to the execution of arbitrary code.

Announced: 2005-09-12
Revised: 2005-09-12
Access: remote
Bugs: #104009
Advisory: https://security.gentoo.org/glsa/200509-08

Affected packages

Package	Arch	Vulnerable	Unaffected
dev-lang/python	*	< 2.3.5-r2	>= 2.3.5-r2

Background

Python is an interpreted, interactive, object-oriented, cross-platform programming language. The "re" Python module provides regular expression functions.

Description

The "re" Python module makes use of a private copy of libpcre which is subject to an integer overflow leading to a heap overflow (see GLSA 200508-17).

Impact

An attacker could target a Python-based web application (or SUID application) that would use untrusted data as regular expressions, potentially resulting in the execution of arbitrary code (or privilege escalation).

Workaround

Python users that don't run any Python web application or SUID application (or that run one that wouldn't use untrusted inputs as regular expressions) are not affected by this issue.

Resolution

All Python users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.3.5-r2"

Bugs: #80592
Advisory: https://security.gentoo.org/glsa/200502-09

Affected packages

Package	Arch	Vulnerable	Unaffected
dev-lang/python	*	<= 2.3.4	>= 2.3.4-r1, >= 2.3.3-r2 (revision), >= 2.2.3-r6 (revision)

Background

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

Description

Graham Dumpleton discovered that XML-RPC servers making use of the SimpleXMLRPCServer library that use the register_instance() method to register an object without a _dispatch() method are vulnerable to a flaw allowing to read or modify globals of the associated module.

Impact

A remote attacker may be able to exploit the flaw in such XML-RPC servers to execute arbitrary code on the server host with the rights of the XML-RPC server.

Workaround

Python users that don't make use of any SimpleXMLRPCServer-based XML-RPC servers, or making use of servers using only the register_function() method are not affected.

Resolution

All Python users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose dev-lang/python
