GHSA-86WM-R4C5-2RC9 Wire Swift runtime: negative LENGTH_DELIMITED length in skipGroup() crashes any protobuf-decoding service

Summary 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...

CVE-2026-61695

The Wire Swift runtime (wire-runtime-swift) is vulnerable to a Denial of Service attack because ProtoReader.skipGroup() fails to reject negative lengths for LENGTH_DELIMITED fields within unknown START_GROUP fields. A crafted 10-byte protobuf payload can cause ReadBuffer.readData(count:) to pass ...

CLSA-2026-1789553486 libxml2: Fix of 2 CVEs

CVE-2026-86143: guard the sizet buffer length against INTMAX before it is narrowed to the int passed to writecallback in xmlOutputBufferWrite, xmlOutputBufferWriteEscape and xmlOutputBufferFlush xmlIO.c, so a negative length can no longer reach an output callback - CVE-2026-86144: propagate the...

com.github.luben/zstd-jni: zstd-jni: Denial of Service via negative length parameter

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...
