Description

This security bulletin contains information about 1 vulnerability.


1) Memory leak (CVE-ID: CVE-2022-22173)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 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


The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in the Public Key Infrastructure daemon (pkid). In a scenario where Public Key Infrastructure (PKI) is used in combination with Certificate Revocation List (CRL), if the CRL fails to download the memory allocated to store the CRL is not released. Repeated occurrences will eventually consume all available memory and lead to an inoperable state of the affected system causing a DoS.
