New Critical Patch Updates or Security Alerts have been issued by Oracle regarding multiple vulnerabilities in libpng.
A memory corruption flaw was found in the way applications, using the libpng library and its progressive reading method, decoded certain PNG images. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash or, potentially, execute arbitrary code with the privileges of the user running the application. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1205 to this issue.
A denial of service flaw was found in the way applications using the libpng library decoded PNG images that have certain, highly compressed ancillary chunks. An attacker could create a specially-crafted PNG image that could cause an application using libpng to consume excessive amounts of memory and CPU time, and possibly crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0205 to this issue.
A memory leak flaw was found in the way applications using the libpng library decoded PNG images that use the Physical Scale (sCAL) extension. An attacker could create a specially-crafted PNG image that could cause an application using libpng to exhaust all available memory and possibly crash or exit. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2249 to this issue.
Additional information about this issue 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.x | Low | Install patch 137080-06 or later. |
| Avaya IR | 3.0, 4.0 | Low | Upgrade to IR 4.0 Service Pack 6 and install "Solaris 10 Patch Cluster (Jan 2012) for Avaya IR 4.0 Service Pack 6" 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-2010-0205 CVE-2010-1205 CVE-2010-2249 |
These are a low as no critical system applications or processes would be affected. |
