This flaw involves a potential out-of-bounds write within the \u003ccode\u003eCipherCtxRef::cipher_update_inplace\u003c/code\u003e function, specifically when processing AES-KW-PAD (AES Key Wrap with Padding) ciphers. \u003ccode\u003erust-openssl\u003c/code\u003e is a Rust-language wrapper for the widely used OpenSSL library, providing cryptographic functionalities to a multitude of applications. The vulnerability indicates that improper handling of memory boundaries during cryptographic operations could occur, potentially leading to data corruption, denial of service, or, in more severe scenarios, arbitrary code execution. This issue affects applications that rely on the \u003ccode\u003erust-openssl\u003c/code\u003e library for cryptographic operations, particularly those utilizing AES-KW-PAD for key wrapping. While details on specific exploitation are not provided, developers and organizations using \u003ccode\u003erust-openssl\u003c/code\u003e should prioritize patching to mitigate risks associated with memory corruption vulnerabilities. This is a critical library component, and even a \u0026quot;potential\u0026quot; issue warrants attention due to its widespread use.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe observed damage from CVE-2026-45784 is currently theoretical, as the advisory details a potential vulnerability rather than active exploitation. However, a successful exploit of an out-of-bounds write in a cryptographic library like \u003ccode\u003erust-openssl\u003c/code\u003e could lead to severe consequences. Attackers might be able to corrupt application data, trigger denial-of-service conditions by crashing vulnerable processes, or potentially achieve arbitrary code execution by manipulating memory in a controlled manner. Given the foundational role of \u003ccode\u003erust-openssl\u003c/code\u003e in securing communications and data, affected organizations could face compromise of sensitive information, disruption of critical services, or the execution of malicious code within their systems. The exact number of potential victims or targeted sectors is unknown, but any application depending on \u003ccode\u003erust-openssl\u003c/code\u003e for AES-KW-PAD operations could be at risk.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePatch CVE-2026-45784 by updating all instances of the \u003ccode\u003erust-openssl\u003c/code\u003e library to the latest patched version immediately.\u003c/li\u003e\n\u003cli\u003eReview applications that utilize the \u003ccode\u003erust-openssl\u003c/code\u003e library, especially those implementing AES-KW-PAD ciphers, to assess exposure and ensure timely updates.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-07-20T07:15:12Z","date_published":"2026-07-20T07:15:12Z","id":"https://feed.craftedsignal.io/briefs/2026-07-rust-openssl-oob-write/","summary":"A potential out-of-bounds write vulnerability, CVE-2026-45784, has been identified in the `rust-openssl` library's `CipherCtxRef::cipher_update_inplace` function when processing AES-KW-PAD ciphers, which could lead to unexpected behavior or potential exploitation by corrupting memory.","title":"Potential Out-of-Bounds Write in rust-openssl AES-KW-PAD Cipher Operations","url":"https://feed.craftedsignal.io/briefs/2026-07-rust-openssl-oob-write/"}],"language":"en","title":"CraftedSignal Threat Feed - Rust-OpenSSL Project","version":"https://jsonfeed.org/version/1.1"}
