Security Bulletin
This security bulletin contains information about 8 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU84603
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-50230
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the handling of the Phone Book Access profile. A remote attacker on the local network can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
