{"id":"UBUNTU-CVE-2026-116133","details":"HTTP::Body versions before 1.23_01 for Perl allow CPU exhaustion via quadratic rescanning of a multipart body with a missing or malformed boundary. Before the first part, and between parts, the multipart parser searches the whole buffered body for the next boundary. On a miss it keeps everything and searches again from the start when the next chunk arrives. A body with no boundary, or with a delimiter followed by neither CRLF nor \"--\", is therefore rescanned on every chunk, taking time quadratic in its size. A remote attacker can exhaust worker CPU with a few such requests.","modified":"2026-11-04T03:30:24.801155305Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-116133"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116133"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116133"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/44711943/"},{"type":"REPORT","url":"https://github.com/libwww-perl/HTTP-Body/commit/bf77eb959bbe1641b77f69eefe98d58ce4c4ec79.patch"},{"type":"REPORT","url":"https://metacpan.org/release/GETTY/HTTP-Body-1.24/changes"}],"affected":[{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.22-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.23-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.23-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}},{"package":{"name":"libhttp-body-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libhttp-body-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.23-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-body-perl","binary_version":"1.23-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116133.json"}}],"schema_version":"1.9.2","severity":[{"type":"Ubuntu","score":"medium"}]}
