**Name of the Vulnerable Software and Affected Versions** llama.cpp versions prior to b5662 **Description** The issue is related to a buffer overflow in the vocabulary-loading code of llama.cpp. An attacker-supplied GGUF model vocabulary can trigger this overflow. Specifically, the helper function `token to piece()` in `vocab.cpp` casts a large `size t` token length into an `int32 t`, causing the length check to be bypassed. As a result, `memcpy` is called with an oversized size, allowing a malicious model to overwrite memory beyond the intended buffer. This can lead to arbitrary memory corruption and potential code execution. **Recommendations** For versions prior to b5662, update to version b5662 to resolve the issue. As a temporary workaround, consider restricting the use of attacker-supplied GGUF model vocabularies to minimize the risk of exploitation.

Name of the Vulnerable Software and Affected Versions: Nuclei versions 3.0.0 through 3.3.1 Description: A vulnerability in Nuclei's template signature verification system could allow an attacker to bypass the signature check and possibly execute malicious code via custom code template. The vulnerability is present in the template signature verification process, specifically in the `signer` package. It stems from a discrepancy between how the signature verification process and the YAML parser handle newline characters, combined with the way multiple signatures are processed. This allows an attacker to inject malicious content into a template while maintaining a valid signature for the benign part of the template. CLI users are affected if they execute custom code templates from unverified sources, and SDK users are affected if they permit the execution of custom code templates by end-users. Recommendations: For versions 3.0.0 through 3.3.1, update to Nuclei version 3.3.2 or later to mitigate the security risk. As an interim measure, refrain from using custom templates if unable to upgrade immediately, and only execute trusted, verified templates. If unable to upgrade Nuclei, disable running custom code templates as a workaround.
