{"id":"AZL-86346","summary":"CVE-2026-7258 affecting package php for versions less than 8.3.31-1","details":"In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, some functions, including urldecode(), pass signed char to ctype functions (like isxdigit()). On the systems with default signed char and optimized table-lookup ctype functions - such as NetBSD - this can lead to accessing array with negative offset, which can trigger a denial of service.","modified":"2026-08-29T05:27:27Z","published":"2026-05-10T05:16:11Z","upstream":["CVE-2026-7258"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7258"}],"affected":[{"package":{"name":"php","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/php"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.31-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86346.json"}}],"schema_version":"1.9.0"}
