Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU25642

Risk: Medium

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-9431

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in LTE RRC dissector within "epan/dissectors/packet-lte-rrc.c". A remote attacker can pass specially crafted data to the application and perform denial of service attack.

Mitigation
