{"id":"UBUNTU-CVE-2026-7179","details":"A security vulnerability has been detected in OSPG binwalk up to 2.4.3. This vulnerability affects the function read_null_terminated_string of the file src/binwalk/plugins/winceextract.py of the component WinCE Extraction Plugin. Such manipulation of the argument self.file_name leads to path traversal. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. The project maintainer confirms this issue: \"I accept the existence of the Path Traversal vulnerability. However, as stated in the Github link, it reached EOL and as a result no actions should be expected.\" The GitHub repository mentions, that \"[u]sers and contributors should migrate to binwalk v3.\" This vulnerability only affects products that are no longer supported by the maintainer.","modified":"2026-05-26T19:29:32.171183222Z","published":"2026-04-27T23:16:00Z","upstream":["CVE-2026-7179"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-7179"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-7179"}],"affected":[{"package":{"name":"binwalk","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.1+dfsg-1","2.0.1+dfsg-2","2.0.1+dfsg-3","2.1.1-1","2.1.1-2","2.1.1-3","2.1.1-4"],"ecosystem_specific":{"binaries":[{"binary_version":"2.1.1-4","binary_name":"binwalk"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.json"}},{"package":{"name":"binwalk","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.1-16"],"ecosystem_specific":{"binaries":[{"binary_name":"binwalk","binary_version":"2.1.1-16"},{"binary_name":"python3-binwalk","binary_version":"2.1.1-16"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.json"}},{"package":{"name":"binwalk","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.2~git20180830+dfsg1-1","2.2.0+dfsg1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2.0+dfsg1-1","binary_name":"binwalk"},{"binary_name":"python3-binwalk","binary_version":"2.2.0+dfsg1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.json"}},{"package":{"name":"binwalk","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.2+dfsg1-1","2.3.3+dfsg1-2"],"ecosystem_specific":{"binaries":[{"binary_name":"binwalk","binary_version":"2.3.3+dfsg1-2"},{"binary_name":"python3-binwalk","binary_version":"2.3.3+dfsg1-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.json"}},{"package":{"name":"binwalk","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.4+dfsg1-1","2.3.4+dfsg1-2~build1","2.3.4+dfsg1-2","2.3.4+dfsg1-3~build1","2.3.4+dfsg1-3","2.3.4+dfsg1-4","2.3.4+dfsg1-4ubuntu1","2.3.4+dfsg1-5"],"ecosystem_specific":{"binaries":[{"binary_name":"binwalk","binary_version":"2.3.4+dfsg1-5"},{"binary_name":"python3-binwalk","binary_version":"2.3.4+dfsg1-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.json"}},{"package":{"name":"binwalk","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.3+dfsg1-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.3+dfsg1-2","binary_name":"binwalk"},{"binary_name":"python3-binwalk","binary_version":"2.4.3+dfsg1-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.json"}},{"package":{"name":"binwalk","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/binwalk?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.3+dfsg1-2","2.4.3+dfsg1-2build1"],"ecosystem_specific":{"binaries":[{"binary_name":"binwalk","binary_version":"2.4.3+dfsg1-2build1"},{"binary_version":"2.4.3+dfsg1-2build1","binary_name":"python3-binwalk"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-7179.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:L/I:L/A:L"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P"},{"type":"Ubuntu","score":"medium"}]}
