{"id":"UBUNTU-CVE-2021-29499","details":"SIF is an open source implementation of the Singularity Container Image Format. The `siftool new` command and func siftool.New() produce predictable UUID identifiers due to insecure randomness in the version of the `github.com/satori/go.uuid` module used as a dependency. A patch is available in version \u003e= v1.2.3 of the module. Users are encouraged to upgrade. As a workaround, users passing CreateInfo struct should ensure the `ID` field is generated using a version of `github.com/satori/go.uuid` that is not vulnerable to this issue.","modified":"2026-03-25T18:29:56.639653Z","published":"2021-05-07T21:15:00Z","upstream":["CVE-2021-29499"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-29499"},{"type":"REPORT","url":"https://github.com/sylabs/sif/security/advisories/GHSA-4gh8-x3vv-phhg"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2021-29499"},{"type":"REPORT","url":"https://github.com/sylabs/sif/commit/193962882122abf85ff5f5bcc86404933e71c07d"}],"affected":[{"package":{"name":"singularity-container","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/singularity-container@2.4.2-4ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.1-2","2.3.2-1","2.4.1-1","2.4.2-2","2.4.2-3","2.4.2-4","2.4.2-4ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"singularity-container","binary_version":"2.4.2-4ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}},{"package":{"name":"golang-github-sylabs-sif","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/golang-github-sylabs-sif@1.0.9-1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.9-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-sylabs-sif-dev","binary_version":"1.0.9-1"},{"binary_name":"siftool","binary_version":"1.0.9-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}},{"package":{"name":"golang-github-sylabs-sif","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-sylabs-sif@1.0.9-2.1ubuntu0.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.9-2.1","1.0.9-2.1build1","1.0.9-2.1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-sylabs-sif-dev","binary_version":"1.0.9-2.1ubuntu0.1"},{"binary_name":"siftool","binary_version":"1.0.9-2.1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}},{"package":{"name":"golang-github-sylabs-sif","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-sylabs-sif@2.8.3-2ubuntu0.24.04.3?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.3-2build1","2.8.3-2ubuntu0.24.04.1","2.8.3-2ubuntu0.24.04.2","2.8.3-2ubuntu0.24.04.3"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-sylabs-sif-dev","binary_version":"2.8.3-2ubuntu0.24.04.3"},{"binary_name":"siftool","binary_version":"2.8.3-2ubuntu0.24.04.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}},{"package":{"name":"singularity-container","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/singularity-container@4.1.1+ds2-1ubuntu0.3+esm2?arch=source&distro=esm-apps/noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.1.1+ds2-1","4.1.1+ds2-1build1","4.1.1+ds2-1ubuntu0.1","4.1.1+ds2-1ubuntu0.2","4.1.1+ds2-1ubuntu0.2+esm1","4.1.1+ds2-1ubuntu0.3","4.1.1+ds2-1ubuntu0.3+esm1","4.1.1+ds2-1ubuntu0.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-sylabs-singularity-dev","binary_version":"4.1.1+ds2-1ubuntu0.3+esm2"},{"binary_name":"singularity-container","binary_version":"4.1.1+ds2-1ubuntu0.3+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}},{"package":{"name":"golang-github-sylabs-sif","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-github-sylabs-sif@2.21.0-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.21.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-sylabs-sif-dev","binary_version":"2.21.0-1"},{"binary_name":"siftool","binary_version":"2.21.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}},{"package":{"name":"singularity-container","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/singularity-container@4.1.5+ds4-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.1.5+ds4-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-sylabs-singularity-dev","binary_version":"4.1.5+ds4-1"},{"binary_name":"singularity-container","binary_version":"4.1.5+ds4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2021/UBUNTU-CVE-2021-29499.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L
