CVE-2023-5841
Description
A vulnerability was found in the Academy Software Foundation OpenEXR and requires that a malicious EXR file image is parsed by the target device or environment using OpenEXR. This issue occurs due to a failure in validating the number of scanline samples of an OpenEXR file containing deep scanline data, allowing a read or write primitive based on the provided EXR file attributes. This flaw could be used to read or write memory to a compromised device through an attacker-placed EXR image.
Statement
The heap-based buffer overflow vulnerability identified in the Academy Software Foundation's OpenEXR image parsing library represents an important security concern due to its potential for severe consequences and wide-reaching impact. By exploiting this vulnerability, attackers can execute arbitrary code or perform unauthorized read/write operations on affected systems. This ability to manipulate system memory poses a significant risk to data integrity, confidentiality, and system stability. Moreover, the vulnerability's presence in a widely-used image parsing library amplifies its severity. The ability to execute such attacks without user interaction, known as a 0-click attack surface, further amplifies the risk.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
