{"id":"AZL-73240","summary":"CVE-2025-14177 affecting package php for versions less than 8.1.34-1","details":"In PHP versions:8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1, the getimagesize() function may leak uninitialized heap memory into the APPn segments (e.g., APP1) when reading images in multi-chunk mode (such as via php://filter). This occurs due to a bug in php_read_stream_all_chunks() that overwrites the buffer without advancing the pointer, leaving tail bytes uninitialized. This may lead to information disclosure of sensitive heap data and affect the confidentiality of the target server.","modified":"2026-04-01T05:22:16.999545Z","published":"2025-12-27T20:15:40Z","upstream":["CVE-2025-14177"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-14177"}],"affected":[{"package":{"name":"php","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/php"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.1.34-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-73240.json"}}],"schema_version":"1.7.5"}
