gnupg: GnuPG: Signature bypass via form feed character in signed messages

A flaw was found in GnuPG. An adversary can exploit this vulnerability by crafting a signed message that includes a form feed character \f at the end of a plaintext line. This allows the adversary to append additional, unsigned text to the message while the signature verification still reports...

CVE-2026-40190

The CVE-2026-40190 issue affects LangSmith JavaScript/TypeScript SDK (langsmith) prior to 0.5.18, where an incomplete prototype pollution fix in the vendored lodash set() allows traversal via constructor.prototype, enabling an attacker who controls data keys processed by createAnonymizer() to pol...

GHSA-F984-PCP8-V2P7 Wasmtime has improperly masked return value from `table.grow` with Winch compiler backend

Impact Wasmtime's Winch compiler backend contains a bug where translating the table.grow operator causes the result to be incorrectly typed. For 32-bit tables this means that the result of the operator, internally in Winch, is tagged as a 64-bit value instead of a 32-bit value. This invalid...

An integer overflow existed in the wolfCrypt CMAC implementation, that could be exploited to forge CMAC tags. The function wcCmacUpdate used the guard if cmac-totalSz != 0 to skip XOR-chaining on the first block where digest is all-zeros and the XOR is a no-op. However, totalSz is word32 and wrap...

CVE-2026-5477

The CVE-2026-5477 issue concerns wolfCrypt CMAC: an integer overflow in wc_CmacUpdate caused by a guard that skips XOR-chaining on the first block when cmac->totalSz != 0. totalSz is a 32-bit value and wraps to zero after 2^28 blocks (4 GiB), which can discard the live CBC-MAC chain state. Thi...

CVE-2026-35186

A flaw was found in Wasmtime, a runtime for WebAssembly. The Winch compiler backend incorrectly handles the table.grow operator, leading to an internal type mismatch. This can result in a Denial of Service DoS, where the host process crashes. Additionally, under specific configurations with...

CVE-2026-34941

A flaw was found in Wasmtime, a runtime for WebAssembly. When transcoding a UTF-16 string to the latin1+utf16 component-model encoding, Wasmtime incorrectly validates the byte length of the input string, checking the number of code units instead of the actual byte length. This vulnerability can...

Wasmtime has data leakage between pooling allocator instances

Impact Wasmtime's implementation of its pooling allocator contains a bug where in certain configurations the contents of linear memory can be leaked from one instance to the next. The implementation of resetting the virtual memory permissions for linear memory used the wrong predicate to determin...

GHSA-QQFJ-4VCM-26HV Wasmtime segfault or unused out-of-sandbox load with `f64x2.splat` operator on x86-64

On x86-64 platforms with SSE3 disabled Wasmtime's compilation of the f64x2.splat WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can result in a uncaught segfault due to loading from unmapped guard pages. With guard pages...
