CVE-2008-5031: Python

High severity, CVSS 10.0. EPSS: 3% chance of exploitation in the next 30 days.

Multiple integer overflows in Python 2.2.3 through 2.5.1, and 2.6, allow context-dependent attackers to have an unknown impact via a large integer value in the tabsize argument to the expandtabs method, as implemented by (1) the string_expandtabs function in Objects/stringobject.c and (2) the unicode_expandtabs function in Objects/unicodeobject.c. NOTE: this vulnerability reportedly exists because of an incomplete fix for CVE-2008-2315.

Affected products

• Python Python: version 2.2.3 only; version 2.3.7 only; version 2.4.6 only; version 2.5.1 only
