Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU67465
Risk: Medium
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-23096
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the DNS proxy dnsproxy.c when handling Header Data in DNS responses. A remote attacker can send specially crafted TCP packets to the affected software, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
MitigationUpdate the affected packages.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Out-of-bounds read
EUVDB-ID: #VU67466
Risk: Medium
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-23097
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the forward_dns_reply() function in the DNS proxy. A remote attacker can send specially crafted TCP packets to the application, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
MitigationUpdate the affected packages.
