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

Description

The 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.

Mitigation

Install updates from vendor's repository.

2) Memory leak

EUVDB-ID: #VU67550

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-2022-38178

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.

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

Description

The 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 when reusing HTTP connection while requesting statistics from the stats channel. A remote DNS server under attacker's control trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.

Mitigation

Install updates from vendor's repository.

5) Memory leak

EUVDB-ID: #VU67547

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-2022-2906

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.
