Description

This security bulletin contains information about 4 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2026-3203)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in the RF4CE Profile protocol dissector. A remote attacker can create a specially crafted packet trace file, trick the victim into opening it, trigger an out-of-bounds read error and cause a denial of service condition on the system.


2) Uncontrolled Memory Allocation (CVE-ID: CVE-2026-3201)

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to USB HID protocol dissector memory exhaustion. A remote attacker can trick a victim to open a specially crafted packet trace file and cause a denial of service (DoS) condition on the target system.


3) Heap-based buffer overflow (CVE-ID: CVE-2026-5405)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the RDP dissector. A remote attacker can trick a victim to open a specially crafted packet trace file, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


4) Path traversal (CVE-ID: CVE-2026-5656)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the Configuration Profile import feature. A remote attacker can trick a victim to import a malformed configuration profile and write arbitrary files on the system, leading to arbitrary code execution.
