New Critical Patch Updates or Security Alerts have been issued by Oracle regarding vulnerabilities in the GSS-API library.
The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1321 to this issue.
Additional information about these issues may be found on the Oracle Sun Product Security Blog website.
Some Avaya system products are delivered with a Solaris Operating System. Actions to be taken on these products are described below.
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya CMS | R15, R16, R16.1, R16.2 | Low | For R15 upgrade to CMS R15ab.m or R15auxab.m or later. For R16.x upgrade to CMS R16.3 or later. |
Recommended Actions:
Avaya strongly recommends that customers follow
networking and security best practices by implementing
firewalls, ACLs, physical security or other appropriate
access restrictions. Though Avaya believes such
restrictions should always be in place, risk to Avaya
products and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as an Avaya provided
product update or the recommended Avaya action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period, but customers should not modify the System Product
operating system or application unless the change is approved by Avaya.
Making changes that are not approved may void the Avaya product service contract.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
| Vulnerability | Mitigating Factors |
|---|---|
| CVE-2010-1321 | This is a low as the package is installed but not used by default. |
