CVE-2007-4965

Status Candidate

Overview

Multiple integer overflows in the imageop module in Python 2.5.1 and earlier allow context-dependent attackers to cause a denial of service (application crash) and possibly obtain sensitive information (memory contents) via crafted arguments to (1) the tovideo method, and unspecified other vectors related to (2) imageop.c, (3) rbgimgmodule.c, and other files, which trigger heap-based buffer overflows.

Ubuntu Security Notice 585-1
Posted Mar 13, 2008
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 585-1 - Piotr Engelking discovered that strxfrm in Python was not correctly calculating the size of the destination buffer. This could lead to small information leaks, which might be used by attackers to gain additional knowledge about the state of a running Python script. A flaw was discovered in the Python imageop module. If a script using the module could be tricked into processing a specially crafted set of arguments, a remote attacker could execute arbitrary code, or cause the application to crash.

VMware Security Advisory 2008-0003
Posted Feb 22, 2008

VMware Security Advisory - This patch fixes a flaw in how the aacraid SCSI driver checked IOCTL command permissions. This flaw might allow a local user on the service console to cause a denial of service or gain privileges. Alin Rad Pop of Secunia Research found a stack buffer overflow flaw in the way Samba authenticates remote users. A remote unauthenticated user could trigger this flaw to cause the Samba server to crash or to execute arbitrary code with the permissions of the Samba server. Chris Evans of the Google security research team discovered an integer overflow issue with the way Python's Perl-Compatible Regular Expression (PCRE) module handled certain regular expressions. If a Python application used the PCRE module to compile and execute untrusted regular expressions, it might be possible to cause the application to crash, or to execute arbitrary code with the privileges of the Python interpreter.

Mandriva Linux Security Advisory - Multiple integer overflows were found 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.

Mandriva Linux Security Advisory - An integer overflow flaw was discovered in how python's pcre module handled certain regular expressions. If a python application using the pcre module were to compile and execute untrusted regular expressions, it could possibly lead to an application crash or the execution of arbitrary code with the privileges of the python interpreter. Multiple integer overflows were found 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.
