OESA-2026-3654 (CVE-2026-52490)
Vulnerability from osv_openeuler – Published: 2026-09-05 15:03 – Updated: 2026-09-05 15:03 – Source websiteThis provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is available on-line in several different formats.And contains command-line programs for manipulating TIFF format image files using the libtiff library.
Security Fix(es):
An issue in libtiff allows an attacker to execute arbitrary code via the process_command_opts() function in tools/tiffcrop.c. The vulnerability is classified as CWE-94 (Code Injection), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.(CVE-2026-52490)
An issue in libtiff 85f2ac8e0b01cb7db2bbecf4a3b891bdbef67938 allows an attacker to execute arbitrary code via the libtiff/tools/thumbnail.c: main() component(CVE-2026-52491)
An integer overflow in the libtiff rgb2ycbcr utility's cvtRaster() function when computing strip buffer sizes can result in an undersized heap allocation and subsequent heap-based buffer overflow during YCbCr conversion of a crafted TIFF image.(CVE-2026-52492)
