Natural Language Toolkit (NLTK) has unbounded recursion in JSONTaggedDecoder.decode_obj() may cause DoS

Summary JSONTaggedDecoder.decodeobj in nltk/jsontags.py calls itself recursively without any depth limit. A deeply nested JSON structure exceeding sys.getrecursionlimit default: 1000 will raise an unhandled RecursionError, crashing the Python process. Affected code File: nltk/jsontags.py, lines...

UltraJSON has an integer overflow handling large indent leads to buffer overflow or infinite loop

Summary ujson.dumps crashes the Python interpreter segmentation fault when the product of the indent parameter and the nested depth of the input exceeds INT32MAX. It can also get stuck in an infinite loop if the indent is a large negative number. Both are caused by an integer overflow/underflow...

Denial Of Service (DoS)

tools.jackson.core, jackson-core is vulnerable to Denial of Service DoS. The vulnerability is due to the UTF8DataInputJsonParser and ReaderBasedJsonParser bypassing the maxNestingDepth constraint when parsing JSON, which allows an attacker to supply excessively nested JSON input that triggers a...

CVE-2026-29062

CVE-2026-29062 affects jackson-core: from 3.0.0 up to before 3.1.0, the UTF8DataInputJsonParser (used when parsing from java.io.DataInput) bypasses the StreamReadConstraints maxNestingDepth (default 500), allowing excessively nested JSON to cause a StackOverflowError and a resulting DoS. A simila...

CVE-2026-29062 jackson-core: Nesting Depth Constraint Bypass in `UTF8DataInputJsonParser` potentially allowing Resource Exhaustion

USN-8056-1: U-Boot vulnerabilities

Simon Diepold discovered that U-Boot incorrectly handled certain DHCP responses. An attacker on the local network could possibly use this issue to obtain sensitive memory contents. CVE-2024-42040 It was discovered that U-Boot incorrectly handled symlink size calculations in squashfs file systems...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in ReaderBasedJsonParser.java and UTF8DataInputJsonParser.java, when processing deeply nested data. A regression in 3.0 versions caused the StreamReadConstraints.maxNestingDepth setti...
