CVE-2009-2411

CVE-2009-2411 describes multiple integer overflows in the libsvn_delta library within Subversion versions prior to 1.5.7 and 1.6.x before 1.6.4. This vulnerability allows remote authenticated users or Subversion servers to execute arbitrary code by sending specially crafted svndiff streams that trigger a heap-based buffer overflow. With a CVSS score of 8.5, this is a high-severity vulnerability, indicating a network-based attack with medium complexity, requiring authentication, and leading to complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
