CVE-2026-5778
Integer underflow leads to out-of-bounds access in sniffer ChaCha decrypt path.
概要
Integer underflow leads to out-of-bounds access in sniffer ChaCha decrypt path.
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
Integer underflow in wolfSSL packet sniffer <= 5.9.0 allows an attacker to cause a program crash in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by ssl_DecodePacket. The underflow wraps a 16-bit length to a large value that is passed to AEAD decryption routines, causing a large out-of-bounds read and crash. An unauthenticated attacker can trigger this remotely via malformed TLS Application Data records.
