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.\r\n\r\nSecurity Fix(es):\n\nAn 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)\n\nAn issue in libtiff 85f2ac8e0b01cb7db2bbecf4a3b891bdbef67938 allows an attacker to execute arbitrary code via the libtiff/tools/thumbnail.c: main() component(CVE-2026-52491)\n\nAn 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)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"libtiff","purl":"pkg:rpm/openEuler/libtiff&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.0-54.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["libtiff-4.3.0-54.oe2203sp4.aarch64.rpm","libtiff-debuginfo-4.3.0-54.oe2203sp4.aarch64.rpm","libtiff-debugsource-4.3.0-54.oe2203sp4.aarch64.rpm","libtiff-devel-4.3.0-54.oe2203sp4.aarch64.rpm","libtiff-static-4.3.0-54.oe2203sp4.aarch64.rpm","libtiff-tools-4.3.0-54.oe2203sp4.aarch64.rpm"],"noarch":["libtiff-help-4.3.0-54.oe2203sp4.noarch.rpm"],"src":["libtiff-4.3.0-54.oe2203sp4.src.rpm"],"x86_64":["libtiff-4.3.0-54.oe2203sp4.x86_64.rpm","libtiff-debuginfo-4.3.0-54.oe2203sp4.x86_64.rpm","libtiff-debugsource-4.3.0-54.oe2203sp4.x86_64.rpm","libtiff-devel-4.3.0-54.oe2203sp4.x86_64.rpm","libtiff-static-4.3.0-54.oe2203sp4.x86_64.rpm","libtiff-tools-4.3.0-54.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3654"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52490"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52491"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52492"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}],"database_specific":{"severity":"Critical"}}
