Vulnerability Title
Eog: eye of gnome: buffer overrun when parsing malicious png files with non-standard iccp chunk
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in Eye of GNOME. When parsing a specially crafted PNG image containing malformed color profile metadata, the application fails to validate chunk boundaries while searching for a null terminator. An attacker could trick a user into opening a malicious image, causing the application to read past the allocated buffer. This issue can lead to an application crash, resulting in a Denial of Service (DoS), or potentially expose sensitive memory contents.
