{"id":"AZL-97029","summary":"CVE-2026-61712 affecting package moby-engine 25.0.3-19","details":"BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. Prior to 0.31.1, BuildKit read attacker-controlled /etc/passwd and /etc/group files without an upper bound while resolving a username to a user identifier or group identifier in executor/oci/user.go and solver/llbsolver/ops/user_linux.go. A malicious base image or build could provide oversized files that exhausted memory during user resolution and caused out-of-memory termination of the buildkitd process. This issue is fixed in version 0.31.1.","modified":"2026-08-30T05:26:50Z","published":"2026-08-19T20:17:19Z","upstream":["CVE-2026-61712"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61712"}],"affected":[{"package":{"name":"moby-engine","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/moby-engine"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"25.0.3-19"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-97029.json"}}],"schema_version":"1.9.0"}
