{"id":"UBUNTU-CVE-2023-45679","details":"stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, but some of the pointers in `f-\u003ecomment_list` are left initialized and later `setup_free` is called on these pointers in `vorbis_deinit`. This issue may lead to code execution.","modified":"2026-01-20T18:11:13.857653Z","published":"2023-10-21T00:15:00Z","upstream":["CVE-2023-45679"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-45679"},{"type":"REPORT","url":"https://securitylab.github.com/advisories/GHSL-2023-145_GHSL-2023-151_stb_image_h/"},{"type":"REPORT","url":"https://github.com/nothings/stb/pull/1557"},{"type":"REPORT","url":"https://github.com/nothings/stb/blob/5736b15f7ea0ffb08dd38af21067c314d6a3aae9/stb_vorbis.c#L3660-L3677"},{"type":"REPORT","url":"https://github.com/nothings/stb/blob/5736b15f7ea0ffb08dd38af21067c314d6a3aae9/stb_vorbis.c#L4208-L4215"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-45679"}],"affected":[{"package":{"name":"libstb","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libstb@0.0~git20190817.1.052dce1-1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20190817.1.052dce1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0~git20190817.1.052dce1-1","binary_name":"libstb-dev"},{"binary_version":"0.0~git20190817.1.052dce1-1","binary_name":"libstb0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45679.json"}},{"package":{"name":"libstb","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libstb@0.0~git20210910.af1a5bc+ds-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20200713.b42009b+ds-1","0.0~git20210910.af1a5bc+ds-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0~git20210910.af1a5bc+ds-1","binary_name":"libstb-dev"},{"binary_version":"0.0~git20210910.af1a5bc+ds-1","binary_name":"libstb0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45679.json"}},{"package":{"name":"libstb","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libstb@0.0~git20230129.5736b15+ds-1.2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20230129.5736b15+ds-1","0.0~git20230129.5736b15+ds-1.1","0.0~git20230129.5736b15+ds-1.2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0~git20230129.5736b15+ds-1.2","binary_name":"libstb-dev"},{"binary_version":"0.0~git20230129.5736b15+ds-1.2","binary_name":"libstb0t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45679.json"}},{"package":{"name":"libstb","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libstb@0.0~git20241109.5c20573+ds-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20240715.f7f20f39fe4f+ds-1","0.0~git20241109.5c20573+ds-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0~git20241109.5c20573+ds-1","binary_name":"libstb-dev"},{"binary_version":"0.0~git20241109.5c20573+ds-1","binary_name":"libstb0t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45679.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
