CVE-2010-1349

CWE-189Published: April 12, 2010· Updated: Jun 16, 2026

10.0

CVSS v3.1

Official Description

Integer overflow in Opera 10.10 through 10.50 allows remote attackers to execute arbitrary code via a large Content-Length value, which triggers a heap overflow.

Technical Analysis

CVE-2010-1349 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2010-1349. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
