Description

The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition on the target system.

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP/2 trailer to trigger an out-of-bounds memory read error and cause the application to crash or obtain potentially sensitive information from services that echo back or otherwise use the trailers.

Mitigation

Install update from vendor's website.
