Description
This security bulletin contains information about 1 security vulnerability.
1) Heap-based buffer overflow (CVE-ID: CVE-2018-10184)
The vulnerability allows a remote unauthenticated attacker to DoS condition on the target system.The weakness exists in the mux_h2.c source code file due to improper H2 frame length checking. The H2 frame length is checked against the max_frame_size setting instead of being checked against the bufsize. A remote attacker can send a request that submits a large H2 frame, trigger heap-based buffer overflow and cause the service to crash.
