Discussion
IBM OS/400 Multiple OSP-CERT Vulnerabilities
IBM OS/400 osp-cert is susceptible to multiple vulnerabilities.
The first identified vulnerability is a flaw in local Certificate Authority certificates. During the creation of these certificates, X.509 basic constraints are not added. Since the local Certificate Authority certificates are not properly identified as valid Certificate Authorities, the proper validation of these certificates is impossible, as is the verification of certificate chains that are derived from it.
The next issue is a failure of the application to properly return renewed certificates once they have been made available. This issue is due to a failure of the application to properly notice altered certificate store files during operation.
There are also multiple unspecified ASN.1 parsing vulnerabilities. No further information about these issues are currently available.
These issues allow attackers to potentially subvert, bypass, or possibly alter the security properties of the cryptographic software. The exact impact and possible attack scenarios are not known at this time.
