A vulnerability was found in VMware ESX Server 3.x (Virtualization Software). It has been classified as problematic. This affects an unknown code block of the component VCB Command Line Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

Certain chunk handlers in libpng before 1.0.29 and 1.2.x before 1.2.21 allow remote attackers to cause a denial of service (crash) via crafted (1) pCAL (png_handle_pCAL), (2) sCAL (png_handle_sCAL), (3) tEXt (png_push_read_tEXt), (4) iTXt (png_handle_iTXt), and (5) ztXT (png_handle_ztXt) chunking in PNG images, which trigger out-of-bounds read operations.

The bug was discovered 10/04/2007. The weakness was presented 09/01/2008 with VMware (Website). The advisory is shared at lists.grok.org.uk. This vulnerability is uniquely identified as CVE-2007-5269 since 10/08/2007. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 4 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 67594 (Oracle Linux 3 / 4 / 5 : libpng (ELSA-2007-0992)), which helps to determine the existence of the flaw in a target environment.
