Deserialization of Untrusted Data

Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Deserialization of Untrusted Data in nltk.picklesec.AllowlistUnpickler, nltk.tokenize.punkt.punktpickleload, and...

CVE-2026-79657

NLTK versions before 3.10.3 contain a remote code execution vulnerability in allowlisted pickle loaders that trust entire module namespaces instead of specific safe callables. Attackers can craft malicious pickle payloads invoking dangerous in-namespace functions like ReppTokenizer.execute and...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: - In the net:sched section, there is a fix for the order of qlen adjustment. - Changes to sch-q.qlen related to qdisctreereducebacklog need to occur before a call to that function. Otherwise, it may fail to notify the parent...

SummaryThe AWS Command Line Interface AWS CLI is a unified tool to manage AWS services from the command line. An issue exists where the EMR SSH helper commands aws emr ssh, aws emr socks, aws emr put, aws emr get passed StrictHostKeyChecking=no to the underlying SSH client, disabling host key...

AZL-92879 CVE-2026-47143 affecting package capstone 4.0.2-4

Capstone is a disassembly framework. Versions prior to 6.0.0-Alpha8 and 5.0.8 have a NULL pointer dereference in modRMRequired and decode when disassembling 3DNow! opcodes 0F 0F in builds compiled with -DCAPSTONEX86REDUCE, allowing a remote attacker to crash any application using the reduced X86...

shell-quote: Quadratic-complexity Denial of Service in `parse()` (CWE-407)

Summary shell-quote's parse finalizes its token list with a reduce that uses Array.prototype.concat as the accumulator. Each prev.concatarg copies the entire growing array, so parse runs in On² in the number of tokens. An unauthenticated attacker who can submit a string to any code path that call...

PYSEC-2026-2984 Apache Fory PyFory Deserialization of Untrusted Data

Fory PyFory's ReduceSerializer could bypass documented DeserializationPolicy validation hooks during reduce-state restoration and global-name resolution. An application is vulnerable if it deserializes attacker-controlled data using PyFory Python-native mode with strict mode disabled and relies o...

PYSEC-2026-1786 Picklescan has a missing detection when calling built-in python idlelib.calltip.Calltip
