New Critical Patch Updates or Security Alerts have been issued by Oracle regarding vulnerabilities in Libexif.
Integer overflow in the exif_data_load_data_entry function in libexif/exif-data.c in Libexif before 0.6.16 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via an image with many EXIF components, which triggers a heap-based buffer overflow. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-4168 to this issue.
Heap-based buffer overflow in the exif_entry_fix function (aka the tag fixup routine) in libexif/exif-entry.c in libexif 0.6.18 allows remote attackers to cause a denial of service or possibly execute arbitrary code via an invalid EXIF image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3895 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 thru R16.3 | Low | Upgrade to R16.3eg.f or later as detailed in PCN1711P |
| Avaya IR | 4.0 | Low | The Libexif package is installed but not used by IR. Therefore Avaya will not test the patches related to this alert. |
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-2006-4168 CVE-2009-3895 |
These are a low as the affected package is installed but not used. |
