Description

This security bulletin contains information about 2 vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2026-25990)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when loading PSD images. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


2) Resource exhaustion (CVE-ID: CVE-2026-40192)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the FITS image decoder when parsing a specially crafted GZIP-compressed FITS file. A remote attacker can supply a specially crafted FITS file to cause a denial of service.

The issue can result in unbounded memory consumption, leading to an out-of-memory crash or severe performance degradation.
