{"id":"AZL-71246","summary":"CVE-2025-66293 affecting package libpng for versions less than 1.6.52-1","details":"LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.52, an out-of-bounds read vulnerability in libpng's simplified API allows reading up to 1012 bytes beyond the png_sRGB_base[512] array when processing valid palette PNG images with partial transparency and gamma correction. The PNG files that trigger this vulnerability are valid per the PNG specification; the bug is in libpng's internal state management. Upgrade to libpng 1.6.52 or later.","modified":"2026-04-01T05:22:30.666404Z","published":"2025-12-03T21:15:53Z","upstream":["CVE-2025-66293"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66293"}],"affected":[{"package":{"name":"libpng","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libpng"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.52-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-71246.json"}}],"schema_version":"1.7.5"}
