Wire Swift runtime: negative LENGTH_DELIMITED length in skipGroup() crashes any protobuf-decoding service

Wire's Swift runtime Wire SPM/CocoaPods product, implemented by wire-runtime-swift did not reject a negative LENGTHDELIMITED field length while skipping an unknown protobuf group. A crafted 10-byte protobuf payload could cause ProtoReader.skipGroup to read a length-delimited field whose varint...

CVE-2026-69210

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, WebSocket FrameTranscoder.bodyLength rejects extended payload lengths above Integer.MAXVALUE but permits negative 64-bit lengths. A remote client that completes a WebSocket handshake through an Ember server can send su...

Astra Linux – Vulnerability in libvirt

A flaw was discovered in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before performing the negative length check by the C API entry points. Passing a negative length to the gnew0 function results in a crash because the negative length is treate...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the ofmodalias function, we can pass the str and len parameters. This could lead to a kernel oops in vsnprintf, as the function only allows passing a NULL pointer when the length is also 0. Additionally, we need to filter out...

Astra Linux – Vulnerability in Thunderbird

A malicious mail server could send malformed strings with negative lengths, causing the parser to read memory outside the buffer. If a mail server or the connection to a mail server were compromised, an attacker could cause the parser to malfunction, potentially crashing Thunderbird or leaking...

CVE-2026-89045

A flaw was found in zstd-jni. This vulnerability allows an attacker to trigger an infinite loop by providing negative length parameters to the ZstdInputStreamNoFinalizer.read method. This can cause the read method to spin indefinitely, holding the stream monitor and blocking other threads from...

CVE-2026-89045

zstd-jni versions 1.4.8-4 through 1.5.7-13 fail to validate negative length parameters in ZstdInputStreamNoFinalizer.read, allowing attackers to trigger infinite loops. Attackers can pass negative length values to cause the read method to spin indefinitely while holding the stream monitor, blocki...
