Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2008-1721
CWEhttps://cwe.mitre.org/data/definitions/681.html

Integer signedness error in the zlib extension module in Python 2.5.2 and earlier allows remote attackers to execute arbitrary code via a negative signed integer, which triggers insufficient memory allocation and a buffer overflow.

Weakness

When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur.
