Description

This security bulletin contains information about 2 vulnerabilities.


1) 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.


2) 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.
