Heartbleed Heartbleed 漏洞 CVE-2014-0160 是 OpenSSL 库中的一个严重实现缺陷，攻击者可借此从受害服务器的内存中窃取数据。窃取的数据内容取决于服务器内存中已有的内容，可能包含私钥、TLS 会话密钥、用户名、密码、信用卡信息等。该漏洞存在于 SSL/TLS 用于保持连接活跃的心跳（Heartbeat）协议的实现中。 受影响的 OpenSSL 版本范围为 1.0.1 至 1.0.1f。Ubuntu 虚拟机中的版本为 1.0.1。 Heartbleed...

EUVD-2026-72341

In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded...

CVE-2026-85437

MOOS-IvP through version 24.8.1 is affected by multiple buffer overflow vulnerabilities in its IvP function string decoders (specifically in FunctionEncoder.cpp). The root cause is that decoders trust attacker-controlled length fields without validation, allowing an attacker to craft malicious en...

DEBIAN-CVE-2026-70405

Improper Validation of Specified Quantity in Input vulnerability in Erlang/OTP snmp allows a remote attacker to degrade availability by sending an SNMP message containing a BER INTEGER whose length field is arbitrarily large. snmppdus:decintegernotag/1 defaults its size limit to infinity, and...

CVE-2026-80594

A flaw was found in the Linux kernel's ims-pcu driver. This vulnerability allows a malicious device to trigger an infinite loop by providing a specially crafted descriptor with a zero-length field during the parsing of CDC union descriptors. This can lead to a Denial of Service DoS condition,...

kernel: net: openvswitch: reject oversized nested action attrs

A flaw was found in Open vSwitch in the Linux kernel. Improper handling of oversized nested action attributes can lead to a truncated length field, which could be exploited by a local attacker to alter kernel memory. This alteration might result in the disclosure of sensitive information or a loc...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the WiMax DLMAP dissector could crash. This issue was addressed in the plugin plugins/epan/wimax/msgdlmap.c by validating the length field...

GHSA-HMQ9-67W8-J5PW netty-incubator-codec-ohttp: BinaryHttpParser should enforce limits for variable lengths fields

We don't enforce any limits for the encoded variable lengths that are used for fields. As the remote peer controls these it's easy for the remote peer to have us buffer data forever and so ultimately OOM...

PT-2026-71267

Name of the Vulnerable Software and Affected Versions IBM Informix affected versions not specified Description Remote code execution is possible in the sq sgkprepare function due to an unchecked length field within the SQL Interface. Recommendations At the moment, there is no information about a...

CVE-2026-15567

A flaw was found in Wildfly. A remote unauthenticated attacker can trigger OutOfMemoryError as CSIv2Util's GSS token decoder reads an attacker-controlled length field without bounds checking and attempts to allocate a byte array of that size...

EUVD-2026-55157

Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError. Thi...

Memory Allocation with Excessive Size Value

Overview org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms. Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the BcKeyStoreSpi.engineLoad method, which sizes buffers for the certificate chain array, encoded...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the processRecord method of DTLSReliableHandshake, where the DTLSReassembler constructor allocates a bytelength buffer directly from the 24-bit handshake length field without checking it...
