The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.
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.
A sensitive information disclosure flaw was found in the way applications using the libpng library processed 1-bit interlaced PNG images. An attacker could create a specially-crafted PNG image that could cause an application using libpng to disclose uninitialized memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2042 to this issue.

Recommended Actions for System Products:
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's product and the surrounding network from this potential
vulnerability may be mitigated by ensuring these practices are implemented
until such time as a product update is available or the recommended action is
applied. Further restrictions as deemed necessary based on the customer's
security policies may be required during this interim period.
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
