Description

This security bulletin contains information about 3 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2026-59956)

CWE-ID: CWE-125 - Out-of-bounds read

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


The vulnerability allows a remote attacker to disclose sensitive information and cause a denial of service.

The vulnerability exists due to out-of-bounds read in IffInput::readimg() when parsing an uncompressed 16-bit IFF image with the ZBUFFER flag set. A remote attacker can trick the victim into opening a crafted IFF file to disclose sensitive information and cause a denial of service.

No configuration prerequisite is required because the IFF plugin is built and loaded by default.


2) Stack-based buffer overflow (CVE-ID: CVE-2026-59181)

CWE-ID: CWE-121 - Stack-based buffer overflow

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


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

The vulnerability exists due to stack-based buffer overflow in CineonInput::open() when parsing a crafted Cineon image file with an unchecked numberOfElements value. A remote attacker can trick the victim into opening a specially crafted .cin file to cause a denial of service or modify data.

User interaction is required to open a crafted file.


3) Uncontrolled Recursion (CVE-ID: CVE-2026-59156)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: CVSS:4.0/AV:L/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 recursion in FitsInput::read_fits_header() in src/fits.imageio/fitsinput.cpp when parsing a crafted FITS file header that lacks the mandatory END keyword. A remote attacker can trick the victim into opening a crafted file to cause a denial of service.

User interaction is required to open the crafted FITS file.
