CVE-2012-1150

Severity CVSS v4.0:
Pending analysis
Type:
CWE-310 Cryptographic Issues
Publication date:

Last modified:

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.

Impact
