CVE-2010-3492

Severity: medium (CVSS 5.0 v2.0)
Exploited in the wild: not listed in CISA KEV
EPSS: 3.2% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2010-10-19 · updated 2026-06-16

Description

The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that terminate these applications via network connections.

Affected products

Python: through 2.7; from 3.0 before 3.1.2 — fixed in 3.1.2

How to fix

Upgrade to a fixed version: Python 3.1.2. Check the vendor advisory for mitigations.
