CVE-2025-28164
Description
A flaw was found in libpng. This buffer overflow vulnerability allows a local attacker to cause a denial of service (DoS) by exploiting the png_create_read_struct() function. This can lead to the affected system becoming unresponsive or crashing.
Statement
This is a MODERATE impact vulnerability affecting libpng versions 1.6.43-1.6.46. A local attacker can exploit a buffer overflow in the png_create_read_struct() function, leading to a denial of service. Exploitation requires the attacker to have local access to the system and provide a specially crafted PNG file.
For java-17-openjdk-headless and java-21-openjdk-headless, while the affected code is present in the bundled sources, it is not exercised by these headless packages.
Mitigation
To mitigate the risk of denial of service, users should avoid processing untrusted PNG image files with applications that utilize libpng. Exercise caution when opening or viewing PNG files from unknown or suspicious sources.
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).

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
