CWE-189Published: August 7, 2009· Updated: Jun 16, 2026
8.5
CVSS v3.1
Official Description
Multiple integer overflows in the libsvn_delta library in Subversion before 1.5.7, and 1.6.x before 1.6.4, allow remote authenticated users and remote Subversion servers to execute arbitrary code via an svndiff stream with large windows that trigger a heap-based buffer overflow, a related issue to CVE-2009-2412.
Technical Analysis
CVE-2009-2411 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.
