pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

CVE-2026-37229

FlexRIC v2.0.0 contains a reachable assertion in e2apcreatepdu triggered when ASN.1 PER decoding fails. A remote unauthenticated attacker can send any non-PER byte sequence e.g., a single 0x00 byte over SCTP to the near-RT RIC port 36421 or iApp port 36422 to crash the process via SIGABRT. The...

FlexRIC security vulnerabilities

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability stems from a failure in ASN.1 PER decoding, resulting in a reachable assertion in e2apcreatepdu. This could allow unauthorized remote attackers ...

CVE-2026-44905

Vanetza is an open-source implementation of the ETSI C-ITS protocol suite. In 26.02 and earlier, a denial-of-service vulnerability was identified in the cryptographic verification pipeline of Vanetza. When processing incoming V2X messages, the ASN.1 decoder accepts the structure as syntactically...

Vanetza 安全漏洞

Vanetza is an open-source implementation of a vehicle communication protocol suite developed by Raphael Riebl. Versions of Vanetza prior to 26.02 contained a security vulnerability. This vulnerability occurred when processing malformed network packets in the ASN.1/OER parsing pipeline, where the...

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion via the toString function in the AST Serialization. An attacker can cause uncontrolled recursion by providing specially crafted input, potentially resulting in resource exhaustion and application unavailability...

Tailored Prompts, Targeted Protection: Vulnerability-Specific LLM Analysis for Smart Contracts

Smart contracts on blockchains are prone to diverse security vulnerabilities that can lead to significant financial losses due to their immutable nature. Existing detection approaches often lack flexibility across vulnerability types and rely heavily on manually crafted expert rules. In this pape...

CVE-2026-6527

A flaw was found in Wireshark, a network protocol analyzer. A local user could be affected by this vulnerability if they open a specially crafted capture file containing malformed ASN.1 PER Abstract Syntax Notation One Packed Encoding Rules protocol data. This could lead to a crash of the Wiresha...

Astra Linux - уязвимость в opensc

A vulnerability was discovered in OpenSC. This security flaw causes a buffer overflow vulnerability in the cardoshaveverifyrcpackage function. An attacker can provide a smart card package with malformed ASN1 data. The cardoshaveverifyrcpackage function scans the ASN1 buffer for two tags, but the...

CLSA-2026-1777545654 cups: Fix of CVE-2026-41079

CVE-2026-41079: limit numbytes for SNMP string values to prevent out-of-bounds read in asn1decodesnmp...

CVE-2026-41305

PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. Versions prior to 8.5.10 do not escape tags,...

EUVD-2026-25383

PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. Versions prior to 8.5.10 do not escape sequences when stringifying CSS ASTs. When user-submitted CSS is parsed and re-stringified for embedding in HTML tags, in CSS...

zeek -- potential DoS vulnerabilities

Tim Wojtulewicz of Corelight reports: A series of DNS messages containing long DNS compression chains can cause Zeek to spend a long time processing packets and potentially crash. Due to the fact that these packets can be received from remote hosts, this is a DoS risk. A specially-crafted LDAP...

The Code Whisperer: LLM and Graph-Based AI for Smell and Vulnerability Resolution

Code smells and software vulnerabilities both increase maintenance cost, yet they are often handled by separate tools that miss structural context and produce noisy warnings. This paper presents The Code Whisperer, a hybrid framework that combines graph-based program analysis with large language...

EUVD-2026-21290

An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...

Type Confusion

Handlebars is vulnerable to Type Confusion. The vulnerability is due to unsanitized handling of pre-parsed AST input in Handlebars.compile, which allows an attacker to inject malicious JavaScript via crafted AST nodes and execute arbitrary code...
