An out-of-bounds access issue was addressed with improved bounds checking. This issue is fixed in tvOS 15.5, iOS 15.5 and iPadOS 15.5, Security Update 2022-004 Catalina, watchOS 8.6, macOS Big Sur 11.6.6, macOS Monterey 12.4. A malicious application may be able to execute arbitrary code with system privileges.

According to its banner, the version of Apple TV on the remote device is prior to 15.5. It is therefore affected by multiple vulnerabilities as described in the HT213254

The remote host is running a version of macOS / Mac OS X that is prior to Catalina Security Update 2022-004.
It is, therefore, affected by multiple vulnerabilities :

  - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many     distant matches. (CVE-2018-25032)

  - A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL     pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for     requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This     issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). (CVE-2021-44224)

  - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser     (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the     vulnerability though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and     earlier. (CVE-2021-44790)

  - In zsh before 5.8.1, an attacker can achieve code execution if they control a command output inside the     prompt, as demonstrated by a %F argument. This occurs because of recursive PROMPT_SUBST expansion.
    (CVE-2021-45444)

  - A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a local     string that leads to a heap of out-of-bound write. This flaw allows an attacker to input a specially     crafted zip file, leading to a crash or code execution. (CVE-2022-0530)

  - The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop     forever for non-prime moduli. Internally this function is used when parsing certificates that contain     elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point     encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has     invalid explicit curve parameters. Since certificate parsing happens prior to verification of the     certificate signature, any process that parses an externally supplied certificate may thus be subject to a     denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they     can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients     consuming server certificates - TLS servers consuming client certificates - Hosting providers taking     certificates or private keys from customers - Certificate authorities parsing certification requests from     subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that     use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS     issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate     which makes it slightly harder to trigger the infinite loop. However any operation which requires the     public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-     signed certificate to trigger the loop during verification of the certificate signature. This issue     affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the     15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected     1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). (CVE-2022-0778)

  - A validation issue was addressed with improved input sanitization. This issue is fixed in iOS 15.3 and     iPadOS 15.3, watchOS 8.4, tvOS 15.3, Safari 15.3, macOS Monterey 12.2. Processing a maliciously crafted     mail message may lead to running arbitrary javascript. (CVE-2022-22589)

  - A logic issue was addressed with improved validation. This issue is fixed in macOS Monterey 12.3. A     malicious application may be able to gain root privileges. (CVE-2022-22665)

  - A carefully crafted request body can cause a read to a random memory area which could cause the process to     crash. This issue affects Apache HTTP Server 2.4.52 and earlier. (CVE-2022-22719)

  - Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered     discarding the request body, exposing the server to HTTP Request Smuggling (CVE-2022-22720)

  - If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems     an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server     2.4.52 and earlier. (CVE-2022-22721)

  - valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes. (CVE-2022-23308)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.6.6. It is, therefore, affected by multiple vulnerabilities:
