{"id":"AZL-38126","summary":"CVE-2024-25629 affecting package ceph for versions less than 18.2.2-1","details":"c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these configuration files has an embedded `NULL` character as the first character in a new line, it can lead to attempting to read memory prior to the start of the given buffer which may result in a crash. This issue is fixed in c-ares 1.27.0. No known workarounds exist.","modified":"2026-04-01T05:12:34.699815Z","published":"2024-02-23T15:15:09Z","upstream":["CVE-2024-25629"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-25629"}],"affected":[{"package":{"name":"ceph","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ceph"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.2.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-38126.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
