Issue summary: A retransmitted QUIC CRYPTO frame can release packet storage while the TLS record layer retains a direct pointer into that storage causing use after free. Impact summary: A malicious QUIC server can cause a heap-use-after-free read in the OpenSSL QUIC client. The server can also identify one allocator-adjacent byte through the client's protected Handshake response. CWE: CWE-416: Use After Free Description: During CRYPTO stream processing, a pointer into the first frame's memory on the stream is lent to the TLS handshake processing. The memory must remain stable until it is processed and released. However the processing of retransmitted CRYPTO frames could release the memory if the retransmitted frame fully overlapped the existing frame. This then causes use-after-free read when the TLS handshake processing continues. The use-after-free read can lead to a Denial-of-Service of the client application or a minor leak of information about the heap memory contents that might be overwritten with other data, subsequently allocated by the application, to the peer. FIPS impact: no The FIPS module is not affected as the QUIC implementation is outside of the OpenSSL FIPS module boundary.

Issue summary: Setting an AES-GCM-SIV IV shorter than the expected nonce length via EVP_CipherInit_ex() may trigger a heap out-of-bounds read. Supplying a longer IV is silently truncated instead of rejected. Impact summary: An application passing a caller-supplied IV of the wrong length may crash or read beyond its buffer. Because trailing IV bytes are ignored, an attacker who knows one message and tag may forge messages under a different IV. CWE: CWE-125: Out-of-bounds Read Description: AES-GCM-SIV copies the caller-supplied IV or nonce into its internal state using a copy whose length is taken from the expected nonce size rather than from the length the caller actually provided. When the caller passes a shorter IV, the copy reads past the end of the caller's buffer; AddressSanitizer confirms a heap out-of-bounds read reached through EVP_CipherInit_ex() into ossl_aes_gcm_siv_init(). When the caller passes a longer IV, the implementation silently discards the trailing bytes instead of rejecting the length. The truncation breaks the binding between the IV and the computed authentication tag. An attacker who has observed a message and its tag under one IV can produce a message and tag that verify under a different IV whose first bytes match, since the surplus bytes never influence the computation. The message itself is unchanged, so this is a failure of IV commitment rather than a classic existential forgery. Only applications that call EVP_CipherInit_ex() (or the equivalent provider cipher initialization) with an IV length other than the standard 12 bytes for AES-GCM-SIV are affected. The severity is limited because the out-of-bounds read is small and attacker-controlled only in length, and the forgery requires an unusual IV length choice by the application. FIPS impact: no The FIPS modules are not affected by this issue, as AES-GCM-SIV is not an approved algorithm.
