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\nA flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).(CVE-2026-12912)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"libtiff","purl":"pkg:rpm/openEuler/libtiff&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.6.0-11.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["libtiff-4.6.0-11.oe2403sp3.aarch64.rpm","libtiff-debuginfo-4.6.0-11.oe2403sp3.aarch64.rpm","libtiff-debugsource-4.6.0-11.oe2403sp3.aarch64.rpm","libtiff-devel-4.6.0-11.oe2403sp3.aarch64.rpm","libtiff-static-4.6.0-11.oe2403sp3.aarch64.rpm","libtiff-tools-4.6.0-11.oe2403sp3.aarch64.rpm"],"noarch":["libtiff-help-4.6.0-11.oe2403sp3.noarch.rpm"],"src":["libtiff-4.6.0-11.oe2403sp3.src.rpm"],"x86_64":["libtiff-4.6.0-11.oe2403sp3.x86_64.rpm","libtiff-debuginfo-4.6.0-11.oe2403sp3.x86_64.rpm","libtiff-debugsource-4.6.0-11.oe2403sp3.x86_64.rpm","libtiff-devel-4.6.0-11.oe2403sp3.x86_64.rpm","libtiff-static-4.6.0-11.oe2403sp3.x86_64.rpm","libtiff-tools-4.6.0-11.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2926"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12912"}],"database_specific":{"severity":"High"}}
