Summary
UMTS FP protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service A flaw was found in Wireshark. This vulnerability allows a remote attacker to cause a denial of service (DoS) by sending a specially crafted Universal Mobile Telecommunications System (UMTS) FP protocol packet.
This can disrupt network analysis operations. While exploitable by a remote attacker, successful exploitation requires a user to either open a malicious capture file or actively capture network traffic containing the crafted packet.
This limits the attack surface to scenarios where Wireshark is actively used for network analysis. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
Weakness: CWE-1286. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE.
Affected products named by the advisory: Red Hat package: wireshark.

Mitigation checklist
- To mitigate this issue, users should avoid opening or analyzing untrusted network capture files with Wireshark. Additionally, consider running Wireshark in a sandboxed environment to limit the potential impact of a crash. If Wireshark is not essential for daily operations, removing the `wireshark` package can eliminate the vulnerability, though this may affect other tools dependent on its libraries.
