Description Robert Frohl 2021-10-05 11:50:34 UTC

moderate: null pointer dereference in h2 fuzzing (CVE-2021-41524)

    While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing,

    allowing an external source to DoS the server. This requires a specially crafted request.

    The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project.
