CVE-2016-9036: An exploitable incorrect return value vulnerability exists in the mp_check function of Tarantool's Msgpuck...

An exploitable incorrect return value vulnerability exists in the mp_check function of Tarantool's Msgpuck library 1.0.3. A specially crafted packet can cause the mp_check function to incorrectly return success when trying to check if decoding a map16 packet will read outside the bounds of a buffer, resulting in a denial of service vulnerability.

Security readout for executives and security teams

CVE-2016-9036 can let a malformed packet crash software that uses Tarantool's Msgpuck 1.0.3 parser. The supplied data points to denial of service, not data theft or code execution, but it is remotely reachable where untrusted packets are parsed. Exposure is likely limited to systems that embed or package Tarantool Msgpuck library 1.0.3 and parse untrusted MessagePack data. Internet-facing APIs, queues, or services accepting MessagePack-like packets would carry the highest availability risk. Treat this as a high-priority availability issue for exposed services using Msgpuck 1.0.3. It is less severe than remote code execution, but a reliable crash in a public service can still create business disruption. Mitigation focus: Inventory applications and dependencies for Tarantool Msgpuck library 1.0.3.; Check Tarantool or Msgpuck vendor guidance for the corrected version or official workaround.; Prioritize remediation for internet-facing services parsing untrusted MessagePack data..

Out-of-bounds Read

Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
