Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Heap-based buffer overflow

EUVDB-ID: #VU12524

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2018-10184

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
