Summary

The Apache Subversion mod_dontdothat module is susceptible to a denial-of-service attack triggered by exponential XML entity expansion. This vulnerability allows an attacker to craft a malicious XML entity that, when processed, leads to excessive consumption of CPU and memory resources in the affected process. This can result in significant disruption of service, making systems unstable and unresponsive. Users of Apache Subversion versions 1.4.0 through 1.8.16, as well as 1.9.0 through 1.9.4, are urged to update to the latest version to mitigate this issue.

Affected Version(s)

Apache Subversion 1.4.0 to 1.8.16
