{"id":"AZL-91436","summary":"CVE-2026-58012 affecting package glib for versions less than 2.78.6-11","details":"A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary.","modified":"2026-09-01T05:28:09Z","published":"2026-06-30T13:19:17Z","upstream":["CVE-2026-58012"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58012"}],"affected":[{"package":{"name":"glib","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/glib"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.78.6-11"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91436.json"}}],"schema_version":"1.9.0"}
