USN-8777-1 bison vulnerability

It was discovered that GNU Bison incorrectly handled grammar-defined configuration variables when generating HTML reports. An attacker could possibly use this issue to execute arbitrary code...

PYSEC-2026-3869 NLTK: Uncontrolled resource consumption in RecursiveDescentParser via ambiguous or left-recursive grammars

nltk.parse.RecursiveDescentParser and SteppingRecursiveDescentParser enumerate parses top-down with no bound on the number of recursive steps. A small, crafted context-free grammar makes a short input consume unbounded CPU and/or exhaust the Python recursion stack, pinning a process indefinitely ...

GHSA-G53G-W8RJ-FMG7 xmldom PI grammar regex ReDoS: quadratic backtracking on unterminated processing instructions

Summary @xmldom/xmldom's processing-instruction PI grammar regex exhibits quadratic-time backtracking ReDoS when parsing an unterminated processing instruction. A single small XML document containing forces the regular expression engine into On² work, stalling the Node.js event loop. The input is...

Uncontrolled Recursion

Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Uncontrolled Recursion via the RecursiveDescentParser in nltk/parse/recursivedescent.py. An attacker can pin a CPU core indefinitely or exhaust...

Name of the Vulnerable Software and Affected Versions @logtape/syslog versions prior to 1.3.11 @logtape/syslog versions prior to 2.0.14 @logtape/syslog versions prior to 2.1.5 Description Two output-encoding issues exist in the structured data formatting code when includeStructuredData is set to...

CVE-2026-75975

fast-uri is a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not validate the complete IPv6 grammar, so invalid trailing text in an authority can be silently discarded and a malformed attacker-controlled host is turned into a different valid IPv6 destination. For...

Zoo Design Studio: Recursive KCL parsing is vulnerable to denial-of-service

Impact Feeding a KCL program that wraps an expression in deep, unnecessary parentheses triggers the parser’s recursive expression - unnecessarilybracketed - expression path. With enough nesting, the call stack grows until it exceeds the process stack limit, causing a stack overflow...

GNU Bison allows for an execution of an arbitrary program during HTML report generation due to improper handling of grammar-defined configuration variables. A grammar file can override the executable used for the XML‑to‑HTML transformation step via %define tool.xsltproc, which is accepted without...

CVE-2026-56389

A flaw was found in GNU Bison. During HTML report generation, the software improperly handles grammar-defined configuration variables. An attacker can provide a specially crafted grammar file that overrides the executable used for XML-to-HTML transformation. This allows for the execution of an...
