Synopsis: Moderate: python security update CVE Names: CVE-2007-2052 python off-by-one locale.strxfrm() (possible memory disclosure) CVE-2007-4965 python imageop module heap corruption CVE-2008-1721 python: integer signedness error in the zlib extension module CVE-2008-1887 python: PyString_FromStringAndSize does not check for negative size values CVE-2008-3142 python: Multiple buffer overflows in unicode processing CVE-2008-2315 python: Multiple integer overflows in python core CVE-2008-3143 python: Multiple integer overflows discovered by Google CVE-2008-3144 python: Potential integer underflow and overflow in the PyOS_vsnprintf C API function CVE-2008-4864 python: imageop module multiple integer overflows CVE-2008-5031 python: stringobject, unicodeobject integer overflows When the assert() system call was disabled, an input sanitization flaw was revealed in the Python string object implementation that led to a buffer overflow. The missing check for negative size values meant the Python memory allocator could allocate less memory than expected. This could result in arbitrary code execution with the Python interpreter's privileges. (CVE-2008-1887) Multiple buffer and integer overflow flaws were found in the Python Unicode string processing and in the Python Unicode and string object implementations. An attacker could use these flaws to cause a denial of service (Python application crash). (CVE-2008-3142, CVE-2008-5031) Multiple integer overflow flaws were found in the Python imageop module. If a Python application used the imageop module to process untrusted images, it could cause the application to disclose sensitive information, crash or, potentially, execute arbitrary code with the Python interpreter's privileges. (CVE-2007-4965, CVE-2008-4864) Multiple integer underflow and overflow flaws were found in the Python snprintf() wrapper implementation. An attacker could use these flaws to cause a denial of service (memory corruption). (CVE-2008-3144) Multiple integer overflow flaws were found in various Python modules. An attacker could use these flaws to cause a denial of service (Python application crash). (CVE-2008-2315, CVE-2008-3143) An integer signedness error, leading to a buffer overflow, was found in the Python zlib extension module. If a Python application requested the negative byte count be flushed for a decompression stream, it could cause the application to crash or, potentially, execute arbitrary code with the Python interpreter's privileges. (CVE-2008-1721) A flaw was discovered in the strxfrm() function of the Python locale module. Strings generated by this function were not properly NULL-terminated, which could possibly cause disclosure of data stored in the memory of a Python application using this function. (CVE-2007-2052) Would like to thank David Remahl of the Apple Product Security team for responsibly reporting the CVE-2008-2315 issue.
