NVD Description
Note: Versions mentioned in the description apply only to the upstream h2o package and not the h2o package as distributed by Debian.
H2O is an HTTP server. In versions 2.3.0-beta2 and prior, when the reverse proxy handler tries to processes a certain type of invalid HTTP request, it tries to build an upstream URL by reading from uninitialized pointer. This behavior can lead to crashes or leak of information to back end HTTP servers. Pull request number 3229 fixes the issue. The pull request has been merged to the master branch in commit f010336. Users should upgrade to commit f010336 or later.
