Description

This security bulletin contains information about 5 vulnerabilities.


1) Buffer over-read (CVE-ID: CVE-2026-70652)

CWE-ID: CWE-126 - Buffer over-read

CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to disclose sensitive information and cause a denial of service.

The vulnerability exists due to a buffer over-read in JPEG gain map encoding when resizing and re-encoding a JPEG with a gain map. A local user can process a specially crafted JPEG through a specific image pipeline to disclose sensitive information and cause a denial of service.

Only libvips instances compiled with support for libultrahdr are vulnerable.


2) Heap-based buffer overflow (CVE-ID: CVE-2026-70653)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to disclose sensitive information.

The vulnerability exists due to a heap-based buffer overflow in the radiance image decoder when parsing a well-crafted run length encoded radiance image. A local user can supply a specially crafted image to disclose sensitive information.

Only libvips builds with support for loading radiance images are vulnerable.


3) Heap-based buffer overflow (CVE-ID: CVE-2026-70654)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 5.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to heap-based buffer overflow in the VipsForeignLoadPpm operation when processing untrusted, uncompressed PPM images from a custom source. A local user can supply a specially crafted PPM image to cause a denial of service.

Only applications that define their own custom libvips sources and use them to process untrusted, uncompressed PPM images are vulnerable.


4) Integer Overflow to Buffer Overflow (CVE-ID: CVE-2026-70651)

CWE-ID: CWE-680 - Integer Overflow to Buffer Overflow

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to integer overflow to buffer overflow in dimension handling in the ImageMagick-based TIFF reader when processing a crafted multi-page TIFF image. A local user can supply a specially crafted multi-page TIFF image to cause a denial of service.

Only libvips builds compiled without libtiff support and with ImageMagick support are vulnerable.


5) Heap-based buffer overflow (CVE-ID: CVE-2026-69242)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service and disclose sensitive information.

The vulnerability exists due to integer overflow leading to a heap-based buffer overflow in libvips TIFF image processing when parsing a crafted many-band TIFF image. A local user can supply a specially crafted TIFF image to cause a denial of service and disclose sensitive information.

Memory may be accessed at attacker-controlled negative offsets within mmap-resident regions, and user interaction is not required.
