{"id":"OESA-2026-2927","summary":"libtiff security update","details":"This  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.\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)","modified":"2026-07-09T13:00:05.954232658Z","published":"2026-07-09T12:52:06Z","upstream":["CVE-2026-12912"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2927"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12912"}],"affected":[{"package":{"name":"libtiff","ecosystem":"openEuler:20.03-LTS-SP4","purl":"pkg:rpm/openEuler/libtiff&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.0-38.oe2003sp4"}]}],"ecosystem_specific":{"src":["libtiff-4.3.0-38.oe2003sp4.src.rpm"],"x86_64":["libtiff-4.3.0-38.oe2003sp4.x86_64.rpm","libtiff-debuginfo-4.3.0-38.oe2003sp4.x86_64.rpm","libtiff-debugsource-4.3.0-38.oe2003sp4.x86_64.rpm","libtiff-devel-4.3.0-38.oe2003sp4.x86_64.rpm"],"aarch64":["libtiff-4.3.0-38.oe2003sp4.aarch64.rpm","libtiff-debuginfo-4.3.0-38.oe2003sp4.aarch64.rpm","libtiff-debugsource-4.3.0-38.oe2003sp4.aarch64.rpm","libtiff-devel-4.3.0-38.oe2003sp4.aarch64.rpm"],"noarch":["libtiff-help-4.3.0-38.oe2003sp4.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-2927.json"}}],"schema_version":"1.7.5"}
