pageant: Out-of-bounds read / oversized allocation in `pageant` MemoryMap::read via a malicious Pageant agent (Windows)

Summary MemoryMap::read in the pageant crate part of the russh workspace, used by russh's SSH-agent client on Windows via AgentClient::connectpageant copies a peer-controlled number of bytes out of an 8192-byte shared-memory view with no bounds check — unlike the sibling MemoryMap::write, which...

CVE-2026-95616

An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation. An unauthenticated attacker can send a SOAP message carrying an X.509 certificate whose SubjectKeyIdentifier extension declares a length of 0x7FFFFFFF; WSS4J decodes this while resolving the signature's...

CVE-2026-102820

The pageant Windows crate (prior to version 0.2.3 ) contains an out-of-bounds read and oversized allocation vulnerability in the MemoryMap::read function located at pageant/src/wmmessage.rs. The root cause is that the function trusts a peer-controlled u32 response length provided via an 8192-byte...

CVE-2026-102820 pageant: Out-of-bounds read / oversized allocation in `pageant` MemoryMap::read via a malicious Pageant agent (Windows)

pageant provides a PageantStream type that implements AsyncRead and AsyncWrite traits and can be used to talk to a running Pageant instance. Prior to pageant 0.2.3, the Windows pageant crate's pageant/src/wmmessage.rs MemoryMap::read function trusts a peer-controlled u32 response length supplied...

A 512-byte workbook can provoke a multi-gigabyte allocation and abort the process

Affected versions passed caller-supplied bytes to calamine's Xlsx::new without first checking that they were a ZIP archive. Xlsx::new tests for password protection on its first line, which parses the input as an OLE/CFB container, and a sector-count field read from the file's own header reaches...

CVE-2026-77322

SIPGO is a library for writing SIP services in the GO language. Prior to 1.4.3, WSConnection.Read in sip/transportws.go creates a wsutil.Reader without setting MaxFrameSize, allowing NextFrame to accept a client-controlled header.Length before ParseMaxMessageLength is applied. An unauthenticated ...

CVE-2026-77322

The SIPGO library (prior to version 1.4.3 ) is vulnerable to a Denial of Service (DoS) attack via unvalidated WebSocket frame lengths. The root cause is located in sip/transport_ws.go, where WSConnection.Read creates a wsutil.Reader without setting the MaxFrameSize parameter. This allows an unaut...

SUSE CVE-2026-54332

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the sFlow ExtendedGatewayFlow decoder in layers/sflow.go reads an attacker-controlled 32-bit community count and AS path member count and sizes a slice allocation from those counts without bounding them against...

CVE-2021-3489 Linux kernel eBPF RINGBUF map oversized allocation

The eBPF RINGBUF bpfringbufreserve function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee "bp...
