{"id":"AZL-91685","summary":"CVE-2026-12912 affecting package gdal 3.6.3-2","details":"A 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).","modified":"2026-08-30T05:24:52Z","published":"2026-06-29T17:16:28Z","upstream":["CVE-2026-12912"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12912"}],"affected":[{"package":{"name":"gdal","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/gdal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.6.3-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91685.json"}}],"schema_version":"1.9.0"}
