Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Memory leak
EUVDB-ID: #VU67549
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-38177
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in the DNSSEC verification code for the ECDSA algorithm. A remote attacker can spoof the target resolver with responses that have a malformed ECDSA signature and perform denial of service attack.
MitigationInstall updates from vendor's repository.

4) Out-of-bounds read
EUVDB-ID: #VU67546
Risk: Medium
CVSSv4.0: 4.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-2881
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
