TITLE:
OS/400 osp-cert Certificate Handling Vulnerabilities

SECUNIA ADVISORY ID:
SA16751

VERIFY ADVISORY:
http://secunia.com/advisories/16751/

CRITICAL:
Moderately critical

IMPACT:
Unknown

WHERE:
>From remote

OPERATING SYSTEM:
OS/400 5.x
http://secunia.com/product/212/

DESCRIPTION:
Some vulnerabilities have been reported in OS/400, with unknown
impacts.

1) The local CA (Certificate Authority) certificates do not contain
the X509 basic constraints extension. This can potentially cause
incorrect verification of certification chains.

2) An error in the certificate store causes an old certificate
associated with an application identifier to be returned even when it
has been renewed.

3) An unspecified error in ASN.1 parsing has an unknown impact.

SOLUTION:
PTFs are reportedly available, which fix these security issues.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
