CVE-2012-1150

Python < 2.6.8, 2.7.x < 2.7.3, 3.x < 3.1.5, 3.2.x < 3.2.3 - Denial of Service via Hash Collision

Title source: llm
STIX 2.1

Description

Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before 3.2.3 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.
