Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-3437

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. A remote user can send specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.


Mitigation

Install update from vendor's website.

3) Integer overflow

EUVDB-ID: #VU69337

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-42898

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to an integer overflow within the S4U2Proxy handler on 32-bit systems. A remote user can send specially crafted request to the KDC server, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.

4) Buffer overflow

EUVDB-ID: #VU69364

Risk: High

CVSSv3.1:

CVE-ID: CVE-2022-44640

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in ASN.1 codec in Heimdal. The ASN.1 compiler generates code that allows specially crafted DER encodings of CHOICEs to invoke the wrong free function on the decoded structure upon decode error. This is known to impact the Heimdal KDC, leading to an invalid free() of an address partly or wholly under the control of the attacker. A remote attacker can execute arbitrary code on the system.


Mitigation

Install update from vendor's website.
