Detailsinfo

A vulnerability, which was classified as problematic, was found in Red Hat Enterprise Linux (version now known). Affected is some unknown processing of the component PNG Image Parser. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
