In FreeBSD 11.3-PRERELEASE before r345378, 12.0-STABLE before r345377, 11.2-RELEASE before 11.2-RELEASE-p10, and 12.0-RELEASE before 12.0-RELEASE-p4, a bug in pf does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet allowing a maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.

The version of Apple iOS running on the mobile device is prior to 26.7.2. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is 15.x prior to 15.8. It is, therefore, affected by multiple vulnerabilities:

  - A validation issue existed in the entitlement verification. This issue was addressed with improved     validation of the process entitlement. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8,     macOS Tahoe 26.7. A malicious app may be able to break out of its sandbox. (CVE-2026-65381)

  - In FreeBSD 11.3-PRERELEASE before r345378, 12.0-STABLE before r345377, 11.2-RELEASE before     11.2-RELEASE-p10, and 12.0-RELEASE before 12.0-RELEASE-p4, a bug in pf does not check if the outer ICMP or     ICMP6 packet has the same destination IP as the source IP of the inner protocol packet allowing a     maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that     would otherwise be unavailable. (CVE-2019-5598)

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - This issue was addressed with additional entitlement checks. This issue is fixed in iOS 27.2 and iPadOS     27.2, macOS Golden Gate 27, macOS Golden Gate 27.2, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27.2,     visionOS 27.2, watchOS 27.2. An app may be able to access sensitive user data. (CVE-2026-112446)

  - An authentication issue was addressed with improved state management. This issue is fixed in iOS 27 and     iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, visionOS 27. An app may be able to     use the Sign In With Apple authentication flow to access the user's Apple Account. (CVE-2026-20683)

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

The version of Apple iOS running on the mobile device is prior to 27. It is, therefore, affected by multiple vulnerabilities.

States in pf(4) let ICMP and ICMP6 packets pass if they have a packet in their payload matching an existing condition. pf(4) does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet. Impact : A maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.

This Solaris system is missing necessary patches to address a critical security update :

  - Vulnerability in the Oracle Solaris product of Oracle     Sun Systems Products Suite (component: Kernel). The     supported version that is affected is 11.4. Easily     exploitable vulnerability allows unauthenticated     attacker with network access via ICMPv6 to compromise     Oracle Solaris. Successful attacks of this vulnerability     can result in unauthorized creation, deletion or     modification access to critical data or all Oracle     Solaris accessible data. (CVE-2019-5598)

The version of the FreeBSD kernel running on the remote host is 11.x prior to 11.2-RELEASE-p10 or 12.x prior to 12.0-RELEASE-p4. It is, therefore, affected by multiple vulnerabilities in pf.
