CVE-2026-104895 jackson-dataformat-smile: unbounded eager byte[] allocation for raw binary in the async parser allows OutOfMemoryError denial of service

The asynchronous Smile parser NonBlockingByteArrayParser uses a raw-binary length prefix taken from untrusted input to allocate a byte before the body is read, with no upper bound and no overflow check. On the raw-binary marker 0xFD, decodeVInt computes value 25 != 0 overflow guard present in the...

Security Bulletin: Uncontrolled Resource Consumption Security Vulnerability in Jackson-core Affects IBM Sterling B2B Integrator and IBM Sterling File Gateway (CVE-2026-0003)

Summary IBM Sterling B2B Integrator and IBM Sterling File Gateway have addressed the security vulnerability Vulnerability Details ID:WS-2026-0003 DESCRIPTION: The non-blocking async JSON parser in jackson-core bypasses the maxNumberLength constraint default: 1000 characters defined in...

Security Bulletin: IBM Terracotta is affected by jackson-core vulnerabilities that could allow attackers to trigger a denial of service via memory or CPU exhaustion by supplying arbitrarily long numbers

Summary IBM Terracotta uses jackson-core as a foundational Java library for parsing and generating JSON data. Vulnerability Details CVEID:CVE-2026-18401 DESCRIPTION: The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in...

com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...

Security Bulletin: Multiple vulnerabilities in jackson-databind impact IBM License Key Server Administration and Reporting Tool and IBM LKS Administration Agent

Summary Multiple vulnerabilities in jackson-databind impact IBM License Key Server Administration and Reporting Tool and IBM LKS Administration Agent. These vulnerabilities have been addressed.
